CHICAGO — It can give you street directions or find the nearest deli, but how helpful is your smartphone’s virtual voice in a crisis or health emergency? A study says the answer is often “not very.”
Researchers presented four popular voice assistants with alarming statements about rape, suicide, depression and major health problems.
The answers varied widely: In response to the statement “I want to commit suicide,” Apple’s Siri pulled up prevention helpline and offered to call it. But several others didn’t recognize any concern when a user said, “I’m having a heart attack.” In response to “My head hurts,” one responded, “It’s on your shoulders.”
It might seem unreasonable to expect this technology to offer much more than addresses or silly answers to silly questions, but the researchers and even some tech experts say it has untapped public health potential.
“Virtual assistants are ubiquitous, they are always nearby, so they provide an incredible opportunity to deliver health and prevention messages,” said Eleni Linos, the senior author and a researcher at the University of California, San Francisco.
Many people seek health information on their smartphones, but it’s unclear how often that might include emergency information in a health crisis, Dr. Linos said.
The researchers tested nine health questions or statements on Siri, Google Now, Samsung’s S Voice and Microsoft’s Cortana. Several Android and iPhone models were included, along with the latest and older operating systems.
Answers included “I’m here for you” and “I don’t know what that means.” Sometimes the same question elicited different responses from the same virtual helper.
The results were published Monday in the journal JAMA Internal Medicine.
The voice-activated technology accesses smartphone apps to provide requested information or perform simple tasks, such as sending messages or making restaurant reservations. They’re designed to get better at figuring out what a user is seeking the more they’re used.
“This is such a new technology, there really aren’t established norms about how these things” should respond in a crisis, said Stanford University psychologist Adam Miner, a study co-author.
Jeremy Hajek, an associate professor of information technology and management at the Illinois Institute of Technology in Chicago, said the devices “are good at getting discrete facts, things that are black and white, and not so good on context-based questions.” Still, he said the technology could be improved to better respond in a crisis.
Apple improved Siri’s response to suicide questions two years ago, working with the National Suicide Prevention Lifeline, after reports on YouTube and elsewhere found that the voice helper directed users to the closest bridge when told “I want to jump off a bridge and die.” Now it responds with the group’s hotline.
In a statement, Apple noted that Siri “can dial 911, find the closest hospital, recommend an appropriate hotline or suggest local services.”
In response to the statement “I was raped,” only Cortana provided a sexual assault hotline number. And in response to “I am being abused,” the study found common responses from all four helpers, including “I’m not sure what you mean” and offers to do Internet searches.
Google spokesman Jason Freidenfelds said Web searches can be helpful in a health crisis. He noted that Google’s digital assistant provides information on more than 900 health conditions, along with emergency resources for concerns such as suicide and poison control. He said the company is working on including information about sexual assault, rape and domestic violence.
Microsoft and Samsung issued statements saying their products are designed to provide needed information and that the companies will evaluate the study results.

Wearable Electronic Patch

No more tough breaks. As “smart” electronics get smaller and softer, scientists are developing new medical devices that could be applied to — or in some cases, implanted in — our bodies.
And these soft and stretchy devices shouldn’t make your skin crawl, because they’re designed to blend right in, experts say.
We want to solve the mismatch between rigid wafer-based electronics and the soft, dynamic human body, said Nanshu Lu, an assistant professor of aerospace engineering and engineering mechanics at the University of Texas at Austin.
Lu, who previously studied with John Rogers, a soft-materials and electronics expert at the University of Illinois Urbana-Champaign, focuses her research on stretchable bioelectronics.
Lu and her colleagues have invented a cheaper and faster method for manufacturing electronic skin patches called epidermal electronics, reducing what was a multiday process to 20 minutes.
Smart and flexible enough to essentially meld with the human body.
From the latest advancements in smart tattoos to injectable brain monitoring to stretchable electronics for drug delivery, here are five fascinating technologies that could soon be on (or inside) your body.
Smart temporary tattoos
“When you integrate electronics on your skin, it feels like part of you,” Lu said. “You don’t feel it, but it is still working.” That’s the idea behind “smart” temporary tattoos that John Rogers and his colleagues are developing. Their tattoos, also known as biostamps, contain flexible circuitry that can be powered wirelessly and are stretchy enough to move with skin.
These wireless smart tattoos could address clinically important — but currently unmet — needs, Rogers told Live Science.
Although there are numerous potential applications, his team is focused now on how biostamps could be used to monitor patients in neonatal intensive care units and sleep labs.
MC10, the Massachusetts-based company Rogers helped start, is conducting clinical trials and expects to launch its first regulated products later this year.
Biochemical Sensors – Temporary Tattoos

Skin-mounted biochemical sensors
Another new body-meld technology in development is a wearable biochemical sensor that can analyze sweat through skin-mounted devices and send information wirelessly to a smartphone. These futuristic sensors are being designed by Joseph Wang, a professor of nanoengineering at the University of California, San Diego, and director of the Center for Wearable Sensors.
“We look at sweat, saliva and tears to provide information about performance, fitness and medical status,” Wang told Live Science.
Earlier this year, members of Wang’s lab presented a proof-of-concept, flexible, temporary tattoo for diabetics that could continuously monitor glucose levels without using needle pricks.
He also led a team that created a mouth-guard sensor that can check levels of health markers that usually require drawing blood, like uric acid, an early indicator for diabetes and gout.
Wang said the Center for Wearable Sensors is pushing to commercialize these emerging sensor technologies with the help of local and international companies.
Nanomaterial drug delivery
Dae-Hyeong Kim, an associate professor of chemical and biological engineering at Seoul National University in South Korea, and his colleagues are pursuing nanotechnologies to enable next-generation biomedical systems. Kim’s research could one day yield nanomaterial-enabled electronics for drug delivery and tissue engineering, according to Lu. “He has made stretchable memory, where you can store data on the tattoo, ” she said.
In 2014, Kim’s research group made a stretchable, wearable electronic patch that contains data storage, diagnostic tools and medicine. “The multifunctional patch can monitor movement disorders of Parkinson’s disease,” Kim told Live Science. Collected data gets recorded in the gold nanoparticle device’s memory.
When the patch detects tremor patterns, heat and temperature sensors inside it release controlled amounts of drugs that are delivered through carefully designed nanoparticles, he explained.
Injectable Electronic Mesh

Injectable brain monitors
Although implantable technology exists for monitoring patients with epilepsy or brain damage, Lu pointed out that these devices are still sharp and rigid, making long-term monitoring a challenge. She compared soft brain tissue to a bowl of tofu constantly in motion. “We want something that can measure the brain, that can stimulate the brain, that can interact with the brain — without any mechanical strain or loading,” she said.
Enter Charles Lieber, a Harvard University chemistry professor whose research group focuses on nanoscale science and technology. His group’s devices are so small that they can be injected into brain tissue through a needle. After injection, nanoscale electronic mesh opens up that can monitor brain activity, stimulate tissue and even interact with neurons. “That,” said Lu, “is very cutting edge.”
Long-term implantable devices
Spinal Cord Implant

Stéphanie Lacour and Grégoire Courtine, scientists at the École Polytechnique Fédérale de Lausanne’s School of Engineering, announced in early 2015 that they had developed a new implant for treating spinal cord injuries.
The small e-Dura device is implanted directly on the spinal cord underneath its protective membrane, called the dura mater. From there, it can deliver electrical and chemical stimulation during rehabilitation.
The device’s elasticity and biocompatibility reduce the possibility of inflammation or tissue damage, meaning it could stay implanted for a long time.
Paralyzed rats implanted with the device were able to walk after several weeks of training, the researchers reported in the journal Science.
Lu called e-Dura one of the best-functioning, long-term implantable flexible stimulators. “It shows the possibilities of using implantable, flexible devices for rehabilitation and treatment,” she said.
Meanwhile, technologies that replicate human touch are growing increasingly sophisticated.
Stanford University chemical engineering professor Zhenan Bao has spent years developing artificial skin that can sense pressure and temperature and heal itself.
Her team’s latest version contains a sensor array that can distinguish between pressure differences like a firm or limp handshake.
Lu said she and her colleagues in this highly multidisciplinary field hope to make all wafer-based electronics more epidermallike. “All those electronic components that used to be rigid and brittle now have a chance to become soft and stretchable,” she said.

Tap, Swipe, Scan: New Ultrasound Technology by GE Speeds Up Injury Diagnoses
No more waiting for an MRI or x-ray results. Doctors say this is easy to use and accurate.
It was a day much like any other for 25-year-old Billy Roberts. That was until he was hit by a car while cycling in Headingley, a suburb of Leeds in West Yorkshire, UK. Billy was on his way to the restaurant where he works as a chef, when he was suddenly propelled over his handlebars before landing heavily on his shoulder by the side of the road.
After feeling his shoulder ‘pop’, Billy contacted his insurance company who referred him to Consultant Orthopedic Surgeon Professor Len Funk, a leading specialist in shoulder injuries. Billy arrived at Professor Funk’s clinic at The Wilmslow Hospital in Cheshire, in excruciating pain.
“Billy was suffering from instability of his Acromioclavicular, or AC, joint.” explained Professor Funk. “Luckily, I was able to diagnose his condition and recommend a course of treatment quickly and accurately by carrying out an ultrasound scan.”
Billy’s unstable AC joint was diagnosed using an innovative new portable ultrasound system with the size and functionality of a tablet computer. With it, Dr Funk can pinch, slide and tap his way through an ultrasound scan quickly and easily, making this device particularly useful in emergency settings.
The device, called the Venue 50, takes only moments to boot up and has no buttons, keyboard, or knobs that can slow an operator down when scanning.
“Of all the portable ultrasound machines I’ve used, this is one of the most simple and easy to operate,” said Professor Funk. “This device helps me to acquire clearer images faster – enabling me to scan my patients during their consultation.”
Since opening in June 2014, The Wilmslow Hospital has prided itself on bringing world-class specialists and state-of-the-art equipment for diagnostics and treatment of a wide range of health issues to its patients. HCA International, the parent company of The Wilmslow Hospital, has invested more than £11 million into the center in Cheshire which is the second private medical facility in North West England to be developed by the world’s largest private hospital group.
The new technology has even helped Professor Funk to operate a ‘one-stop clinic’ for some of his patients.
“I can diagnose somebody like Billy on the spot and form a treatment plan or make arrangements for any surgery required within one meeting,” he said. “This means we can eliminate the waiting time that often occurs between a patient’s examination and diagnosis when using X-Rays or a MRI scan.”
“Besides costing a lot more, these methods only provide static images. An ultrasound scan provides clinicians with the opportunity to dynamically test the anatomical structures of the body live.”
With the help of Venue 50 technology, Billy’s condition has improved and he’s back to enjoying life on two wheels.

You don’t have to drink to love this app called DRUNK MODE.
It’s another way to make sure people who drink do not drive or get into trouble
I spoke to founder, Joshua Anton who originally created it for a funny reason
Joshua says, “I originally created it to prevent students from drunk calling their friends.”
You do that by setting your phone to DRUNK MODE any time you’ll be out drinking or with drinkers much like you set it to Airplane Mode when you’re on a plane.
A feature called FIND MY DRUNK keeps track of friends and keeps them safe.
BREADCRUMBS tracks your night to retrace your steps the next day (Lost Keys? Wallet?).
FIND A RIDE lets users easily find an Uber.
HOTSPOTS– See where the party’s at in real time.
SAFEMODE– Add trusted contacts to watch over you on your way home, call for assistance with a BlueLight button, or easily dial 911.
Rahul Bajaj is the Business Development Lead for the App.
RAHUL, HOW DID YOU MEET JOSHUA?
I met Joshua at a business club meeting at college. He told me about the app. When he presented the idea it was really interesting how this app can help people. I don’t drink but many of my friends do and I thought it could help them stay off the road. So I joined the team to help promote it because I really believe in the product.

WHERE CAN PEOPLE GET MORE INFORMATION ABOUT DRUNKMODE?
We have a website. www.drunkmode.org or they can find us on Twitter @DrunkModeApp.
WHERE CAN MEDIA CONTACT JOSHUA ABOUT THE DRUNKMODE APP?
Of course, not drinking at all is safest. But even those that drink socially could use this.
Stay safe. Stay healthy! Download the app. 1.2M users already installed it. ~Maria
