Wireless,biodegradable, flexible arterial-pulse sensor monitors blood flow

Zhenan Bao and colleagues have developed a wireless, battery-free, biodegradable sensor to provide continuous monitoring of blood flow through an artery.  This could provide critical information to doctors after vascular, transplant, reconstructive and cardiac surgery, with out the need for a visit. Monitoring the success of surgery on blood vessels is difficult, as by the […]

Neural signals translated into speech

Columbia University’s Nima Mesgarani is developing a computer-generated speech method for those who are unable to talk. How brain signals translate to speech sounds varies from person to person, therefore computer models must be trained individually. The models are most successful when used during open skull surgeries, to remove brain tumors or when electrodes are […]

Fingertip wearable measures disease-associated grip strength

IBM researchers are studying grip strength, which is associated with the effectiveness of Parkinson’s drugs, cognitive function in schizophrenics, cardiovascular health, and elderly mortality. To better understand these markers, Steve Heisig, Gaddi Blumrosen and colleagues have developed a prototype wearable that continuously measures how a fingernail bends and moves. The project began as an attempt to […]

Wearable haptic feedback/stimulation band to address Parkinson’s symptoms

Microsoft has submitted a patent application for a wearable band that uses haptic feedback for stimulation when wrapped around limbs or joints.  It is meant to alleviate Parkinson’s symptoms, including tremors and muscle stiffness. Haptic actuators are distributed across a band that is adjusted to a  “duty cycle” which responds to data derived from wearable […]
