A Temporary Tattoo That Senses Through Your Skin - IEEE Spectrum via @IEEESpectrum

A tiny Biostamp can’t cut off blood flow. It can, however, measure the pulse at two points, just a centimeter or so apart. With this information, a smartphone can calculate a physiological indicator called pulse-wave velocity, which varies as blood pressure changes. So researchers Tony Banks, SeungMin Lee, and Matt Pharr in Rogers’s group are developing two types of Biostamp pulse detectors. One uses light; it alternately flashes a red and an infrared LED and uses a photodetector to pick up the light reflected from the skin beneath the Biostamp. Because deoxygenated blood absorbs more red light and oxygenated blood absorbs more of the infrared, fluctuations in those levels create a waveform that represents the heartbeat. That’s basically how the newest fitness bands detect a pulse, though the Biostamp version can get a more stable signal because the skin doesn’t shift unde...
