摘要: | 為了克服感測器整合於物聯網應用之困難,本論文利用噴印技術研發了四種
氣體感測材料,如二氧化碳、二氧化氮、甲醛、濕度。藉由噴印技術與高分子材 料所具有的特點,例如低製作成本、低功耗的特性,使其易與無線網路系統整合。 此外,藉由噴印式氣體感測材料、自供電無線傳輸模組、太陽能板、自製壓電式 能源擷取器之整合也證實了噴印式高分子感測器應用於物聯網的潛力。 此研究針對導電及非導電高分子材料進行研發作為噴印式感測材料之應用。 混合不同的奈米粒子提升感測材料之感測特性。為了瞭解感測材料之感測機制也 針對這些材料進行材料分析,如傅立葉紅外線轉換光譜儀、紫外線可見光譜儀, 並且驗證了噴印式感測材料之靈敏度及選擇性測試。這些高分子感測材料也被證 實僅需數十微瓦功率便能運作。藉由這些研究成果,化學感測之應用可朝新一代 物聯網邁進。 To conquer obstacles in design-implementation of sensors for Internet-of-Things (IoT) applications, in this dissertation, four kinds of printable ambient gas sensors, i.e. CO2, NO2, formaldehyde, and humidity, were investigated. By employing printing technologies and functional polymer materials, several key features, e.g. low power consumption, low manufacturing cost, and easy integration with network system, can be obtained. Furthermore, the potential of printable polymer sensor for IoT application was also demonstrated by an implementation of a self-powered wireless sensor module integrated with an off-the-shelf solar panel and a self-developed piezoelectric energy harvester. To develop the proposed printable polymer sensing materials, both conductive and dielectric polymers were investigated. Mixed with metal oxide based nanoparticles, sensing characteristics of the developed sensing materials can be improved. To investigate the possible sensing mechanisms of the developed sensing materials, material analyses, such as fourier transform infrared spectroscopy (FTIR) and ultraviolet-visible spectroscopy (UV-vis), were employed. In addition, sensitivity and selectivity were tested to validate the developments of proposed printable sensors. The developed polymer sensors were also verified to have tens of micro-watt power consumptions. With these developed works, chemical sensing capabilities of next generation IoT applications can carry forward. |
