Abstract

Previous research that has focused on TENGs have lacked the proper application of this energy generator. Currently, heart disease remains the leading cause of death in the United States. With increasing demand for self-sustainable medical devices, this nitinol health monitor sensor device (NHMS) integrates the TENG applications with medical applications. The NHMS features memory shape nitinol electrodes that preserves the device structure while using PDMS and PVDF triboelectric effect to measure heart rate, blood pressure, and breathing patterns. Three constant pressures were measured in this study. At a constant pressure of stage 1, the NHMS produces an average AC of .31 volts. At stage 2, the NHMS produced .49 volts, and at stage 3, the NHMS produced .71 volts. Several beats per minute (bpm) were measured and clear readings were obtained from 30 bpm to 180 bpms. Furthermore, additional applications for energy harvesting and defibrillator capabilities are explored. Implications are discussed.
