제목 Melt Blown Thermoplastic Polyurethane and Polypropylene Mat-Based Triboelectric Sensor for Respiration and Heartbeat Monitoring
초록 Nonwoven flexible textile materials thermoplastic polyurethane (TPU) and polypropylene (PP) were used to fabricate a self-powered triboelectric pressure sensor which effectively determined the heartbeat and respiration rate of a human subject. TPU and PP intrinsically owns opposite triboelectric polarity and nonwoven construction of the material accelerated the efficiency of the sensor. The sensor exhibited significant amount of output voltage. Peak to peak voltage (Vp-p) of around 3.3 V was obtained from prototype sensor using custom-made dynamic tester under periodic external load of 0.1~1.0 kgf. Physiological sensor successfully converted human body generated low frequency physio-mechanical vibrations into electrical signal which was received through Piezo Film Lab Amplifier equipped with BIOPAC MP150. From recorded signal, convoluted respiration and heartbeat frequencies were isolated and evaluated.
