Abstract
An organic electrical device can include a first dielectric substrate including a PVDF-TrFe-CFE terpolymer, a first semiconductor region coupled to a first surface of the first dielectric substrate, and a first gate region coupled to a second surface of the first dielectric substrate, the second surface opposite the first surface and opposite the first semiconductor region. The organic electrical device can include an organic field-effect transistor (OFET), comprising the first gate region, the first dielectric substrate, a first source region, and a first drain region respectively electrically coupled to the first semiconductor region. An electrostrictive actuator or mechanical sensor can be co-integrated on the first dielectric substrate, the actuator or sensor including first and second conductive regions located on opposite surfaces of the first dielectric substrate. The actuator or sensor can be electrically coupled to the OFET, and controlled at least in part by the OFET.
