A Wearable Pressure Sensor Based on the Array of Polymeric Piezoelectric Fiber with Metal Core

A wearable pressure sensor is developed based on the array of polymeric piezoelectric fiber with metal core covered by beta phase polyvinylidene fluoride layer. Each fiber consists of a polyester-imide enameled copper core, a piezoelectric layer and sputtered gold electrode. Fiber array is fixed on an insulating substrate and well packaged to ensure stable work. This pressure sensor is tested to declare high sensitivity and fast response. Meanwhile, flexibility of this structure indicates its potentiality to be wearable.
