Document Type and Number:
WIPO Patent Application WO2003085685
Kind Code:
A3
Abstract:
The present invention relates to a contact sensor (50) that detects contact between two objects (52, 56) and includes a first conductor (52) separated from a second conductor (56) by a crushable layer (54) with a predetermined crush resistance. The crushable layer (54) deforms under pressure such that a signal passes between the first and second conductor (52, 56). Methods of detecting contact are also part of this invention.
