Title:
ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/219040
Kind Code:
A1
Abstract:
This electronic device comprises: a secondary battery having a first principal surface and a second principal surface aligned in the Z-axis direction; a rigid body facing the first principal surface; and a sensor that is attached to the rigid body and detects the elastic deformation of the rigid body caused by a force applied to the rigid body. The sensor does not overlap with the secondary battery when viewed in the Z-axis direction, and the first waveform of the signal output by the sensor when the first principal surface is in contact with the rigid body and the first pattern of force is applied to the rigid body is different from the second waveform of the signal output by the sensor when the first principal surface is not in contact with the rigid body and the first pattern of force is applied to the rigid body.
