Stretchable fingernail sensors for measurement of fingertip force


This paper describes a novel stretchable fingernail sensor for measuring fingertip forces for human-computer interaction. The fingernail sensor uses photoplethysmography to measure the change in blood perfusion in the fingernail bed when the fingerpad touches a surface with various forces. The original fingernail sensor was rigidly attached to the human… (More)
