| 中文摘要 | 本研究以奈米金顆粒沉積於PDMS基板，成功開發出高靈敏壓電型應變感測器，並順利量測人體各部位脈搏及其波形。藉由奈米金表面活性劑之碳鏈長度與懸浮液之pH值與奈米金濃度等參數控制，gauge factor可優化至677 (拉伸模式)與338 (壓縮模式)。 |
| 英文摘要 | In this study, highly-sensitive piezoresistive strain sensors based on gold nanoparticle thin films deposited on a stretchable PDMS substrate by centrifugation were developed to measure arterial pulse waveform. By controlling carbon chain length of surfactants, pH value and particle density of the colloidal solutions, the gauge factors of nanoparticle thin film sensors can be optimized up to 677 in tensile mode and 338 in compressive mode, and the pressure sensitivity up to 350. Low pH and thin nanoparticle films produce positive influences to superior gauge factors. It has been demonstrated that nanoparticle thin film sensors on PDMS substrates were successfully applied to sense arterial pulses in different body positions, including wrist, elbow crease, neck, and chest. |
