Flexible Sensor for Human Monitoring System by Using P(VDF/TrFE) Thin Film

Continuous monitoring of human physical and mental conditions are heavily required solving issues to realize a high QoL (quality of life) society. The human condition data especially, heartbeat, ECG (electrocardiogram), respiration and blood pressure are very important vital signs to prevent a human sudden disease, such as a heart attack. In this study, we fabricated a novel sensor to monitor the heartbeat and respiration, which is made on a flexible thin film of P(VDF/TrFE) as a sensing material and PDMS (polydimethylsiloxane) as a substrate material. The PDVF (polyvinylidene fluoride) that is thin, flexible and piezoelectric material can be used for the flexible force sensor. The fabrication steps and some experimental results for human monitoring system are described.
