Overcoming Printing and Interfacial Challenges in Liquid Metal Direct Writing for Integrated Stretchable Electronics

Advanced Materials Technologies, EarlyView.
Liquid metal direct writing is advanced from a technological and fundamental point. Utilizing a kinematic bed, printing on large surfaces with irregularities is enabled. Furthermore, a pressure‐driven flow during printing is discovered that affects the thickness of traces.

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

Advanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Ocean Ambient Noise Study in the Vicinities of Taiwan: Data Analysis and Numerical Modeling

, 2007
本研究為瞭解臺灣鄰近海域的環境噪音之變動特性，對主動式聲納和被動式聲納的偵測距離之影響，利用ASIAEX、VANS和OAJEX等實驗所蒐集的環境噪音資料，以統計方法分析噪音位準的變動特性。首先由ASIAEX在大陸棚海域的觀測數據之分析結果顯示：風浪影響環境噪音的最低頻段約為500 Hz；風浪噪音在頻譜位準的衰減斜率將隨海況而變動；以1k Hz的風浪噪音觀察高低海況的噪音位準之標準偏差值，當風速在5 m/s以上時噪音的變動明顯降低；而隨著統計時間越長則噪音位準的變動可能越大，因此提高了噪音位準的不確定性 ...
