In this study, we report a multi-functional elbow & kneepad system. We introduced the humidity, temperature, textile-based touchpad and bending sensor on the elbow pad while introducing the counter and generator&heater system on the kneepad. Firstly, the swelling of PVA which caused the resistance gone up was used in the humidity sensor. The PVA-copolymer will absorb the water which will make the swelling, and leads the resistance gone up. Secondly, the Carbon Ink&PEDOT coated Nylon11-SEBS filament can sensing when wire bending. Thirdly, we dipping the textile in the Carbon Ink&PEDOT solution to make it conduction. Finally, the kneepad principle is the piezoelectrical property. We use the sponge-PVDF-sponge layer to enhance the piezoelectrical effect which is a benefit to detect the kneecap bending. In front of the kneecap, we set the PVDF generator & heater system, which can receive electric energy through the piezoelectrical effect and store it in the capacitor.
