Soft skin patch could provide early warning for strokes, heart attacks

UC San Diego engineers developed a soft, stretchy ultrasound patch that can be worn on the skin to monitor blood flow through vessels deep inside the body. Such a device can make it easier to detect cardiovascular problems, like blockages in the arteries that could lead to strokes or heart attacks.

Calling all couch potatoes: this finger wrap can let you power electronics while you sleep

A new wearable device turns the touch of a finger into a source of power for small electronics and sensors. Engineers at the University of California San Diego developed a thin, flexible strip that can be worn on a fingertip and generate small amounts of electricity when a person’s finger sweats or presses on it. What’s special about this sweat-fueled device is that it generates power even while the wearer is asleep or sitting still.

Wearable Electronics for Continuous Cardiac, Respiratory Monitoring

A small and inexpensive sensor, announced in Applied Physics Letters and based on an electrochemical system, could potentially be worn continuously by cardiac patients or others who require constant monitoring. A solution containing electrolyte substances is placed into a small circular cavity that is capped with a thin flexible diaphragm, allowing detection of subtle movements when placed on a patient’s chest. The authors suggest their sensor could be used for diagnosis of respiratory diseases.

Bristol innovation challenges regular touchscreens with new spray-on technique

A team at Bristol has challenged the idea that touchscreens are limited to 2D and rectangular shapes by developing an interactive display that can be sprayed in any shape.
Inspired by the way an artist creates graffiti on a wall and using a novel combination of sprayable electronics and 3D printing, the technique, called ProtoSpray, allows the creation of displays on surfaces that go beyond the usual rectangular and 2D shapes.
