Magnetic Array Assisted Triboelectric Nanogenerator Sensor for Real-Time Gesture Interaction
Nano-Micro Letters, 2021 In human-machine interaction, robotic hands are useful in many scenarios. To operate robotic hands via gestures instead of handles will greatly improve the convenience and intuition of human-machine interaction. Here, we present a magnetic array assisted

Optimization of array geometry for direction-of-arrival estimation using a priori information [PDF]
Advances in Radio Science, 2010 This paper focuses on the estimation of the direction-of-arrival (DOA) of signals impinging on a sensor array. A novel method of array geometry optimization is presented that improves the DOA estimation performance compared to the standard uniform linear

Optimal design of on‐scalp electromagnetic sensor arrays for brain source localisation [PDF]
Human Brain Mapping, 2021 AbstractOptically pumped magnetometers (OPMs) are quickly widening the scopes of noninvasive neurophysiological imaging. The possibility of placing these magnetic field sensors on the scalp allows not only to acquire signals from people in movement, but also to reduce the distance between the sensors and the brain, with a consequent gain in the signal ...
