Title:
PRESSURE SENSOR USING MAGNETIC FIELD
Document Type and Number:
WIPO Patent Application WO/2024/058559
Kind Code:
A1
Abstract:
The present invention relates to a pressure sensor using a magnetic field. The present invention provides a pressure sensor using a magnetic field, the pressure sensor comprising: an elastic unit including a magnetic material having a residual magnetization value; and a circuit unit generating a Hall voltage when the magnetic field changes. When at least a part of the elastic unit is deformed according to an external pressure to change the magnetic field applied to the circuit unit, the magnitude of the Hall voltage corresponding to the change in the magnetic field in the circuit unit is detected.
