Abstract
A force sensitive touch sensor (100) is provided. The sensor (100) comprises an insulating support layer (101) and an electrically conductive sensor structure (102). The electrically conductive sensor structure (102) comprises a piezoresistive material and is configured to provide a resistance varying in response to a force being applied to the insulating support layer (101). The piezoresistive material comprises graphene.
