Abstract
This paper presents a degradable nanofibers-based sensor for underwater pressure monitoring applications. The presented capacitive pressure sensor uses polyhydroxy butyrate (PHB) nanofibers as the dielectric material. The sensor is encapsulated in polyimide (PI) to prevent moisture permeation during the operation. The fabricated device is tested in air and water ambient under dynamic and static conditions. The sensor showed a sensitivity of 3.87 kPa−1 with excellent linearity (99.8%) and stability, and low hysteresis of 1.3 %. The fabrication process used here could also be replicated to develop flexible pressure sensors for underwater wearables.
