Abstract

Technological advances have profoundly influenced the design of wearable and flexible electromechanical sensors in piezoelectric materials technology. This article investigates the enhancement of the piezoelectric performance of polyvinylidene difluoride (PVDF) with the addition of nanosilica (SiO2). The use of nanoparticles can overcome the difficulties associated with PVDF, and the touch sensor was fabricated using a sandwich-based assembly. A comparison of the piezo potential generated across the fabricated sensor samples with and without nanofiller was conducted. The experimental results demonstrate that the nanosilica addition improves the piezo-response of the touch sensor and thus has a promising application in the biomedical field.
