Proof-of-Concept of POF-Based Pressure Sensors Embedded in a Smart Garment for Impact Detection in Perturbation Assessment

This paper presents the proposal of intensity variation-based POF pressure sensors embedded in a smart garment for impact detection in perturbation assessment. The proposed system presents low cost and is based on multiplexing technique using side-coupling light source. In addition, it is able to acquire the optical power variation when the pressure on the sensor is applied and to detect the region where the perturbation occurred. Then, a proof-of-concept test was performed with application of pressure on different sensors which show the ability of the system to identify the impact region in a wearable device during a perturbation protocol.
