Fast and Highly Accurate Body-Monitoring Finger Sensor

Researchers at Harvard's School of Engineering have developed safe and accurate force and strain sensors that can be attached directly to fingers for monitoring. The devices can work continuously for extended periods of time, measuring the force and strain values with almost no lag time. This is an impressive achievement, as similar previously developed devices were slow to respond and their output didn't change linearly in proportion to the forces felt. Moreover, the conductive liquid th...
