Protective and Collision‐Sensitive Gel‐Skin: Visco‐Elastomeric Polyvinyl Chloride Gel Rapidly Detects Robot Collision by Breaking Electrical Charge Accumulation Stability

Advanced Intelligent Systems, EarlyView.
For safe human–robot collaboration (HRC), a protective and collision‐sensitive robot skin is proposed. The developed robot skin, named Gel‐Skin, is composed of polyvinyl chloride (PVC) gel, which is a functional material with impact absorption capability and tunable piezoresistive characteristics based on electrical charge‐accumulation.

Evaluation of multi‐user multiple‐input multiple‐output digital beamforming algorithms in B5G/6G low Earth orbit satellite systems

International Journal of Satellite Communications and Networking, EarlyView., 2023
In this paper, we investigate the application of signal‐to‐leakage‐plus‐noise ratio (SLNR) beamforming to low Earth orbit non‐terrestrial networks. The SLNR criterion aims at maximizing the received desired signal power for each user while minimizing the overall interference power caused by each user to all other co‐channel receivers. We show that such

GaAs Growth on Ge‐Buffered Discontinuous (111)‐Faceted V‐Groove Silicon Substrates

Advanced Physics Research, EarlyView.
This work demonstrates antiphase boundary (APB)‐free GaAs growth on Ge buffers formed on discontinuous (111) V‐groove Si substrates. By tailoring the Ge buffer morphology to form well‐defined facets, APB formation is suppressed. This approach offers alternative solutions to achieving APB‐free III–V integration on CMOS‐compatible on‐axis silicon without
