Abstract
In recent years, pressure sensing technologies have made remarkable advancements in the biomedical engineering realm. These advancements have expanded the applications of pressure sensing, leading to the continuous evolution of these technologies. These sensors have a versatile range of applications, from detecting changes in concentrated volumes of liquids to gases, and some are used to identify cardiac anomalies like arrhythmias. This investigation focuses on a dual layer dielectric structure constructed of self healing polydimethylsiloxane (PDMS) and polyvinylidene difluoride (PVDF) fiber electrodes. The PDMS layer is composed through a 3D printed mold which serves as the foundation upon which PDMS is applied to. Following the application, silver nanowires are cured on the surface before being peeled apart from the mold. Furthermore, the second layer intertwines the creation of PVDF fiber electrodes, which are electrospun. After the PDMS and PVDF electrodes are composed, they are attached together and encapsulated with Kapton tape to ensure an airtight seal and copper tape to allocate for capacitance measurements. Different capacitance measurements are obtained through a digital multimeter, with measurements being taken as force is applied. This study aims to determine these readings as a comparison for the individual PVDF and PDMS layers against the dual layer.
