“…EAPs have the potential to be used in a wide range of applications, including actuators for robotics, medical devices, and sensors for detecting changes in pressure, force, and strain, etc. [19][20][21][22][23]. In the recent past, it has been observed that elastomer-based strain sensors attracted researchers' attention due to their wide applications in human activity monitoring, human-machine interface (HMI), rehabilitation, health monitoring, exoskeletons, assistive technology, augmented/virtual reality, soft robotics, and so on [24][25][26][27][28].…”

This paper aims to enhance the capacitance of electroactive polymer (EAP)-based strain sensors. The enhancement in capacitance was achieved by using a free-standing stretchable polymer film while introducing conducting polymer to fabricate a hybrid dielectric film with controlled conductivity. In this work, styrene-ethylene-butylene-styrene (SEBS) rubber was used as the base material, and dodecyl benzene sulfonate anion (DBSA)-doped polyaniline (PANI) was used as filler to fabricate a hybrid composite conducting film. The maleic anhydride group of the SEBS Rubber and DBSA, the anion of the polyaniline dopant, make a very stable dispersion in Toluene and form a free-standing stretchable film by solution casting. DBSA-doped polyaniline increased the conductivity and dielectric constant of the dielectric film, resulting in a significant enhancement in the capacitance of the EAP-based strain sensor. The sensor presented in this article exhibits capacitance values ranging from 24.7 to 100 µF for strain levels ranging from 0 to 100%, and sensitivity was measured 3 at 100% strain level.
