One Per Cent: Hairy sensors to give robots sensitive skin: Similar to their organic counterparts, the 50-nanometre-wide hairs of Suh's device twist and bend against each other when an external force like a beating heart or a soft touch is applied.
The contact between the hairs generates an electrical current which the sensor identifies as specific changes in pressure, shear or torsion...
... It could detect the dynamic motion of a tiny water droplet bouncing on a hydrophobic plate and the physical force of a heartbeat....
