Title:
MEASUREMENT APPARATUS AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/055673
Kind Code:
A1
Abstract:
A measurement apparatus (100), comprising: a fixed end (11) comprising a transmitting coil (111) and a receiving coil (112); a movable end (12) moving relative to the fixed end (11) and comprising a metal conductor (121); and a processor (13) separately coupled to the transmitting coil (111) and the receiving coil (112), wherein when the movable end (12) moves relative to the fixed end (11), the processor (13) applies an alternating signal to the transmitting coil (111), the movable end (12) generates an alternating magnetic field in response to the alternating signal, the receiving coil (112) senses the alternating magnetic field to generate a sensing signal and transmits the sensing signal to the processor (13), and the processor (13) determines the amount of movement of the movable end (12) relative to the fixed end (11) according to the sensing signal. A first sensing signal and a second sensing signal are generated by using the transmitting coil (111), the receiving coil (112) and the metal conductor (121), metal interference can be resisted, the reliability of displacement measurement is improved, and the reliability of the measurement apparatus (100) is further improved. Also provided is an electronic device comprising the measurement apparatus (100).
