Miniature Lung-Heart Sensor on a Chip

The core mechanism of a miniature sensor on a chip incorporates two layers of silicon that overlay each other separated by the space of 270 nanometers — about 0.005 the width of a human hair. They carry a minute voltage. Vibrations from bodily motions and sounds put part of the chip in flux, making the voltage flux and creating readable electronic outputs. In human testing, the chip has recorded a variety of signals from the mechanical workings of the lungs and the heart with clarity — signals that often escape meaningful detection by current medical technology.
