A Tech Brief featured in our October issue showcases how University of Missouri researchers are creating pencil-drawn sensors. The engineers demonstrated that the simple combination of pencils and paper could be used to create personal, health-monitoring devices.

Pencil-drawn graphite patterns serve as conductive traces and sensing electrodes, and office-copy papers work as flexible supporting substrates. The enabled devices can then perform real-time, continuous, and high-fidelity monitoring of a range of vital biophysical and biochemical signals from human bodies, including skin temperatures, heart rates, and sweat.

What do you think? Will We Someday 'Draw' Sensors On Our Skin?
