Durable Tactile Glove for Human or Robot Hand

A glove containing force sensors has been built as a prototype of tactile sensor arrays to be worn on human hands and anthropomorphic robot hands. Whereas the force sensors of a prior force-sensing glove are mounted on the outside, the force sensors of this glove are mounted inside, in protective...
