A transparent stretchable (TS) capacitive sensor, which can detect pressure (force) and touch inputs distinguishably was fabricated by forming with a TS dielectric layer sandwiched between the upper piezoresistive electrode of poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate)–ionic liquid composite enabling to distinguish touch and pressure stimuli and the lower TS electrode of metal/indium tin oxide/metal multilayer on a transparent elastomeric substrate with stress-relieving three-dimensional microstructured pattern providing multi-directional stretchability and high pressure sensitivity. The TS sensor array demonstrated a good control of the interaction with a small vehicle as a multi-functional input device for future wearable electronics.
