Abstract: We propose a one-millimeter-scale linear ultrasonic motor and its feedback control system with a Hall sensor. The size of the stator measures 1.6 mm in height, 1.6 mm in width, and 0.3 mm in ...
Getting started with Arduino can feel quite overwhelming at first because you're faced with the decision of what board to buy ...
A Novel EFPI Sensor for Ultrasonic Testing of Partial-Discharge in High-Voltage Electrical Equipment
Abstract: A novel extrinsic Fabry–Perot interferometric (EFPI) ultrasonic sensor is developed that can detect ultrasonic signals of partial discharge (PD) in high-voltage electrical equipment under ...
