Researchers from Georgia Institute of Technology have developed a sensor chip smaller than a ladybug that monitors lung and heart signals along with body movements and could pave the way to socially distanced health monitor ways in the future. The sensor chip includes two finely developed layers of silicon, which overlap each other and are separated by the space of 270 nanometers. The chip records the vibrations that it receives from inside the body and avoids distracting noise from outside the body’s core like airborne vibrations. The monitoring equipment is currently battery-powered and uses a second chip called a signal-conditioning circuit to interpret the sensor chip’s alerts into patterned read-outs.
