Skin-like, Wearable Pressure Sensor
Stanford researchers have developed a wearable, flexible, high sensitivity pressure sensor that provides information about cardiovascular health, emotional state, and other aspects of human physiology. Attached like a medical bandage, the ultra-thin sensor measures pulse waveforms over arteries or veins with high repeatability (> 3000 cycles). Bio-inspired microstructures enhance the skin-device interface and amplify the signals of physical forces.
Wearable, pressure sensor applied to detect neck pulse
In proof of concept, researchers applied the sensors on the skin over arterial or venous sites to measure pulse waveforms. The waveforms provide important cardiovascular information for healthcare monitoring. Integrated into a simple, portable transmitter and receiver, the device can quickly diagnose cardiovascular and cardiac illnesses.
