臺灣博碩士論文加值系統

隨著生活水準的提升，醫療衛生長足的進步使得全球普遍人類壽命逐漸延長，我國在少子化的趨勢下逐漸進入「高齡化社會」，預計於2026年更將走入「超高齡社會」。人口老化帶來的失能人口數增加亦日益嚴重，需專人照護的老年人逐漸增加，導致國內長照機構設立亦逐年地增加。由於國內長照機構人力缺乏，而相關照護人力無法跟上長照機構設立，及相關輔助設備(如持續性生命現象偵測儀器)不足之情況下，若住民處於瀕臨死亡邊緣時，而無在黃金時間內急救時，則造成機構與家屬之議端。本研究開發結合靜電紡絲技術生產PVDF纖維，以標準三明治結構製備智慧布料感測器；利用近場式與遠場式靜電紡絲技術製作PVDF纖維作為主要之感測材料，並使用三種不同量測方法檢測感測器之訊號，第一種利用標準週期性動態量測平台施加相同應力於不同面積與不同重量百分比濃度PVDF纖維之感測器表面上，觀察纖維面積大小於電壓輸出訊號之差別；第二種實驗利用標準線性滑軌拉伸力量測平台，針對感測器施以軸向拉伸與釋放兩種不同運動，透過不同拉伸速度與拉伸長度，量測不同重量百分比濃度之PVDF纖維智慧布料感測器之輸出訊號結果；第三種實驗方法則是利用標準週期性動態拉伸力量測平台，以週期激振器往復地拉伸感測器，透過不同拉伸頻率0.5 Hz、0.33 Hz與0.2Hz (模擬人體呼吸急促、正常與緩慢之情境)及不同拉伸長度，探討不同重量百分比濃度之PVDF纖維智慧布料感測器，是否能夠辨別呼吸頻率及其靈敏度，此PVDF纖維布料感測器若配合後端電路讀取系統與雲端管理服務，將能夠提供長期照護服務機構具低成本、低人力與減少醫療糾紛之穿戴式醫療輔具，作為新型持續性生命現象之監控感測器。

The improvements in living standards and healthcare has led to an overall increase in life expectancy. This should result in Taiwan having an “ultra-aged society” by 2026 with the proportion of elderly citizens estimated to reach 20.63%. The problem of disability caused by the aging of the population is getting worse with a large number of elderly citizens in need of constant care. Consequently, the number of long term healthcare agencies and old age homes providing continuous care and support is increasing each year. To ensure effective care of these residents by giving medical treatment as soon as it is required, it is critical to monitor their vital signs like heart rate and breathing patterns continuously in real time. Based on the above demographic trends and demands of the long-term agencies, in this project we propose the development of a novel wearable sensor based on piezoelectric electrospinning for breathing detection as an alternative to traditionally used equipment that are bulky and expensive. This research is based on using polyvinyl (PVDF) fibers obtained via electrospinning as the primary sensing element. The abdominal expansion and contraction during respiratory breathing causes stretching of the PVDF fibers that results in a voltage output based on the piezoelectric effect. We use a conductive stretchable fabric for charge extraction that is aimed to provide comfort and suitability for long term wearable application, which use different weight percentage of PVDF powder to make a smart fabric sensor that can distinguish the different frequencies 0.5 Hz, 0.33 Hz and 0.2 Hz (Simulate the shortness, normal and slow situation of human breathing) of human’s breathing patterns, this study is able to integrate with IOT solutions in the future to achieve wearable medical aids as a novel real-time monitoring dection of breathing patterns sensor.
