Interface electronics for tactile sensing arrays

This paper presents the interface electronics design and implementation of a tactile sensing system for humanoid robot applications. The tactile system is designed to cover the human tactile sensing bandwidth ranging from 1Hz to 1kHz and to operate on a wide range of input forces/pressures. Some interface electronics prototypes have been designed and fabricated. The paper reports the experimental results and the validation of the proposed implementation. We report also results of the electro-mechanical response of the tactile sensing system (i.e. tactile sensing array + interface electronics) to external mechanical stimuli. The current implementation is a first step towards dedicated IC integration.
