The auxetic structure improves sensor performance compared to regular substrate.

About

Description: Flexible, stretchable, highly sensitive and low-cost pressure sensors are key elements in advancing wearable or implantable measuring devices. The present invention provides a flexible piezoresistive sensor that exhibits improved piezoresistive sensitivity over other conventional flexible sensors currently available. The sensor is based on 3D porous auxetic materials and conductive materials coating layers. The sensing mechanism is the piezoresistivity of the conductive coating. The auxetic materials provide the overall sensing environment, and the unique auxetic properties enable high sensor sensitivity and larger sensing range. Advantages: The auxetic structure improves sensor performance compared to regular substrate. The unique auxetic properties, such as synclastic curvature, enable the fabrication of large area sensors of complicated contours and ensure accurate detection of signals. Applications: Wearable sensors Sports protection equipment Medical devices Underwater ultrasonic transducer
