Researchers at the FAMU-FSU College of Engineering have developed a soft and stretchable electronic component that improves measurement accuracy and holds a longer charge.
Wearable devices use light-emitting diodes (LEDs) to project light onto human tissues and a photodiode to detect the light. The intensities and waveforms of this interaction correlate to cardiovascular changes in the body. Many of these devices use rigid LEDs and photodiodes embedded in a stiff material like a watchband. The researchers have developed a soft, stretchable photodiode, embedded in an elastic polymer matrix, as an alternative.
Every Wednesday is Wearable Wednesday here at Adafruit! We’re bringing you the blinkiest, most fashionable, innovative, and useful wearables from around the web and in our own original projects featuring our wearable Arduino-compatible platform, FLORA. Be sure to post up your wearables projects in the forums or send us a link and you might be featured here on Wearable Wednesday!
