Design and Characterization of a Tactile Sensor Array
Project Description

A tactile sensor detects not only “touch” but also the magnitude of the touching force. Its deployment can significantly enhance man-machine interaction, in gaming, health care systems and robotics, etc. Traditional tactile sensors require the integration of two disparate technologies, one for constructing the control electronics and the other for building the sensing devices. Hitherto they have been mostly separately implemented before their integration in a package. This approach results in increased cost and reduced reliability. A new technology for constructing a tactile sensor array is presently proposed, allowing the monolithic integration of the control electronics and the sensing device on the same substrate. This approach allows the construction of tactile sensor system with reduced cost and enhanced reliability.
