We develop compact electronics and optics for monitoring health on the body. This includes circuits that measure tissue impedance at MHz frequencies and isolate the pulsatile signal from blood flow, low-force sensors calibrated with neural networks, a miniaturized short-wave infrared spectrometer for diffuse-light measurements, and optical measurements of blood.
