Flexible sensors to track vital signs of the human body

Vertically stacked three-dimensional sensors exhibit low resistance, and consume less power and space1.

The sensors are implantable and potentially useful for monitoring activities of brain cells, heart rates and body temperature.

Current techniques stack sensors horizontally with a lot of wiring. Besides taking up space, they generate noise that attenuates desired signals.

Researchers from King Abdullah University of Science and Technology (KAUST), Saudi Arabia, have overcome these shortcomings by vertically placing sensor electrodes and electronics through polyimide, a chemically inert and stable polymer on a silicon substrate. read more
