Abstract
A haptic touch interface having simultaneous sensing and actuation including an insulating substrate having a front surface and a rear surface and one or more front surface electrodes connected to the front surface of the substrate, wherein the front surface electrodes are arranged in a first pattern. The touch interface further includes one or more rear surface electrodes connected to the rear surface of the substrate, wherein the rear surface electrodes are arranged in a second pattern and the front surface electrodes have a substantial mutual capacitance with the rear surface electrodes. Flying logic is used to control voltages applied to at least one of the front and rear surface electrodes.
