Lung-Heart Super Sensor on a Chip

A sensor chip smaller than a ladybug records multiple lung and heart signals along with body movements and could enable a future socially distanced health monitor. The chip, which acts as an advanced electronic stethoscope and accelerometer in one, is aptly called an accelerometer contact microphone. It detects vibrations that enter the chip from inside the body while keeping out distracting noise from outside the body’s core like airborne sounds.
