Design and implementation of sensing devices have been driven by the need for high sensitivity, low cost, and simple fabrication. Ionic liquids have some desirable properties for soft sensor design in terms of their volatility and conductivity. By applying low cost and simple fabrication methods, we present a multifunctional pressure and temperature sensor. Preliminary results show a sensitivity of 0.24 × 10−3 kPa−1 and −17,000 ppm/K for pressure and temperature respectively. Showing high promise for the presented ionic liquid in soft sensor design. Further investigation into the measuring method, structure, and working principle of the materials involved could provide a higher quality multimodal and multifunctional device.
