Title:
STRESS SENSOR, MANUFACTURING METHOD OF STRESS SENSOR AND SENSOR SHEET
Document Type and Number:
Japanese Patent JP2023037259
Kind Code:
A
Abstract:
To provide a highly accurate stress sensor which can detect the pressure and shear force and which is more miniaturized and highly integrated.SOLUTION: A stress sensor comprises: a plurality of detection units; and an insulation layer or base material arranged between the plurality of laminated detection units. The detection unit comprises: one or two or more pressure detection parts in which a pressure sensing layer is arranged between two electrodes arranged so as to oppose to each other to detect the pressing force; and one or two or more shear force detection parts in which a shear force sensing layer is arranged between two electrodes arranged so as to oppose to each other to detect the shear force. The plurality of laminated detection units are constituted by two types of an integral detection unit including one layer of the pressure sensing layer or the shear force sensing layer and a joint type detection unit including the pressure sensing layer or the shear force sensing layer in which two layers of sensing layers arranged so as to oppose to each other are joined to each other.SELECTED DRAWING: Figure 1A
