Parameter optimization and characteristic analysis of tangentially magnetized reverse-salient permanent magnet synchronous motor

Discover Applied Sciences
Reverse-salient permanent magnet synchronous motors have reverse-salient characteristics, and the direct-axis inductance is larger than the quadrature-axis inductance. Compared with the traditional positive-salient permanent magnet synchronous motor, the

Liquid Crystal Elastomer Actuator Matrix for Large Area Applications

Advanced Materials Technologies, EarlyView.
A scalable approach is used to manufacture a digitally‐controllable, 2D 5 × 5 actuator matrix. The elements of the matrix are produced by direct ink writing of a liquid crystal elastomer ‘artificial muscle’ on large‐area flexible thin‐film heaters. In optimizing the low‐power actuators, multiple heater designs and substrate materials are investigated ...

Spatially Configurable Conformal Sensor Integration on an Ultra‐Fine Metallic Needle for Minimally Invasive Deep‐Tissue Oxygen Monitoring

Advanced Materials Technologies, EarlyView.
A multi‐point oxygen‐sensing ultra‐fine needle (MO‐UFN) is developed by conformally integrating a lithographically patterned flexible electrochemical sensor array onto a clinical acupuncture needle. The platform preserves an approximately 0.3 mm diameter while enabling spatially resolved oxygen profiling along the insertion pathway.

Terahertz Phase Inversion via Field‐Free Spin‐Orbit Torque Switching in an Antenna‐Integrated Spintronic Heterostructure

Advanced Optical Materials, EarlyView.
This work demonstrates fast electrical control of the phase of broadband terahertz pulses using a field‐free spintronic emitter. An antenna‐integrated Ta/CoFeB/Pt heterostructure switches its magnetization through spin‐orbit torque with 1 μs$\umu{\rm s}$ electrical pulses, producing complete π$\pi$‐phase inversion without external magnetic fields ...
