Monitoring of various human motions in real time. (a) Relative resistance changes versus time caused by respiration. (b) Relative resistance changes versus time caused by eye movement; the inset shows the wearable sensor attached to the forehead for monitoring eye movement. (c) Relative resistance changes versus time caused by speaking. (d) Relative resistance changes versus time for large-scale bending and stretching of the finger knuckle; the inset shows the wearable sensor mounted on a glove for monitoring forefinger motion.
