l   宗旨

2013 年多位在微機電領域有豐富經驗的清大教授,於科技部的支持下成立「微感測器與致動器產學聯盟(Micro Sensors and Actuators Technology Consortium, mSAT)。多年來聯盟透過整合學研界的資源和經驗,協助業界解決技術問題、提供設備支援、及技轉和人才培育等,也陸續邀請數十位國內外微系統專家學者,舉辦專題演講。今年因為疫情趨緩,聯盟準備開始舉辦活動,促進國內產學研界的交流,歡迎參加。



l   演講內容

Energy harvesting from human motion is suitable for powering battery-less wearable devices. In such applications, electret energy harvesters (EH) have advantages over other type of EHs due to the fact that low-frequency motion is dominant. In this talk, development of new electret materials based on quantum chemical analysis and machine learning are presented, and their application to rotational/stretchable electret EH are introduced.

In the last 90 years since the first development of electret using Carnauba wax, electret materials have been developed by heuristic approach. In the present study, for the first time, a novel high-performance amorphous fluorinated polymer electret based on quantum chemical analysis and machine learning is proposed. A new electret material based on CYTOP thus obtained offers a record-high surface charge density with extremely-high thermal stability of implanted charges. In addition, novel stretchable electret material based on amorphous fluorinated polymer is also discussed.

As an application of the developed CYTOP electret, a novel low-profile rotational electret EH is prototyped. Output power up to 1 mW has been obtained at a low rotational speed of 1 rps with only 3 mm in thickness. Evaluation of the rotational EH for human walking is also discussed.
