Abstract
In one aspect, the present invention relates to a pressure sensing/force generating device comprising a non-planar substrate, a printed pressure sensitive element comprising (a) a piezoelectric material containing ink composition capable of producing a piezoelectric effect/piezoresistive effect and/or (b) a dielectric material containing ink composition capable of producing a capacitive effect. It also includes a first printed electrode comprising a conductive ink composition, and a second printed electrode comprising a conductive ink composition. The first and second electrodes are in electrical contact with the printed pressure sensitive element. The first and second printed electrodes and the printed pressure sensitive element collectively form a pressure sensitive junction, which is coupled to the non-planar substrate. The present invention further relates to medical devices comprising the pressure sensing/force generating device and methods of making such devices.
