|Abstract:||Pressure analyses play a crucial role in the automotive and medical industries. Pressure sensors in the medical industry are used for minimally invasive surgeries and the self-monitoring of vital signals without the aid of a healthcare professional. The fabrication of smaller pressure sensors can lead to increased comfort during surgery and an improved surgical experience for doctors, and more importantly, patients. This paper introduces five microporous capacitive pressure sensors made from microporous polydimethylsiloxane dielectric layers and copper electrodes. To achieve higher sensitivity, granulated sucrose was added to the pre-polymer base and curing agent of varying weight ratios. The most sensitive device was tested at the physiological temperature of 37 °C, mimicking a surgical environment. The best sensitivity of S = 0.023 kPa-1 was achieved over a pressure range from 0 to 174 kPa. The performance of the pressure sensors described here show promise for use in surgical and non-invasive pressure sensing.|
