| Description | Journal: Flexible and Printed Electronics Recent studies, in the field of safety in the workplace, are focused on developing new sensors and procedures to detect and monitor the body stress due to repeated or highly stressful movements that, in the long term, could lead to painful traumas or accidents. Today, the common method used to evaluate risk activities is based on evaluations that are subjective or supported by difficult and time-consuming video analysis. However, recent developments in wearable sensors, in particular on pressure sensors, allow for innovative alternatives. The main requirements of wearable pressure sensors are a good wearability, to allow natural movements and a sensor response in a broad range of pressure, to allow monitoring a large variety of possible activities. In this paper, we report on a new promising class of textile pressure sensors based on the employment of a conductive polymer that can be easily deposited directly on the fabric, for example used to fabricate sensorized gloves to monitor the hand's stress during manual activity. The main advantages of the proposed technology regard the possibility to selectively tune the pressure response range, adapting it to possible different applications, by changing the formulation of the conductive polymer while leaving the same device architecture and structures. We deposit and characterize the active sensing layer, analyze the pressure sensor response and propose an interpretation of the obtained results, based on piezoresistive phenomena. We identify three different contributions to the sensor output, related to the macroscale, microscale and nanoscale, respectively. Finally, we describe the production of sensorized textile gloves with fully textile pressure sensors that result comfortable, reproducible, low cost and easily tunable in pressure range response. |
