Advanced Materials, EarlyView.Inspired by the octopus and the golden wheel spider, soft robots with liquid crystal elastomer arc fibers as appendages are fabricated to transcend surface constraints through an elevated center of mass and minimal contact footprints. By leveraging curvature‐encoded deformation‐recovery cycles, these robots exhibit contractile, torsional, and flexural ...

Reference Spur Reduction Techniques for a Phase-Locked Loop
IEEE Access, 2019 This paper presents the reference spur reduction techniques for an analog phase-locked loop (PLL). A simple leakage compensation loop is proposed, which cancels the leakage current of the PLL loop filter with a negligible power overhead.

A grid frequency estimation method based on moving average filter half-tangent phase-locked loop
Diance yu yibiaoThis paper proposes a half-tangent phase-locked loop (HTan-PLL) with a moving average filter (MAF) for estimating grid frequency. The proposed PLL utilizes a half-tangent phase detector (PD) and introduces MAF into the phase-locked loop to address ...

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 ...
