Title:
ELECTRONIC CIRCUIT SYSTEM AND METHOD OF MANUFACTURING ELECTRONIC CIRCUIT SYSTEM
Document Type and Number:
Japanese Patent JP2020012739
Kind Code:
A
Abstract:
To provide an electronic circuit system which is excellent in detection sensitivity.SOLUTION: An electronic circuit system includes: a piezoelectric sensor in which electrical displacement is generated in response to strain caused by an external force and which is formed by winding a piezoelectric body around a core material; a circuit board connected to the sensor; and a coating layer covering at least the sensor. The coating layer has a Young's modulus at 23°C of 0.02 MPa or more and 2000 MPa or less and contains a resin having a haze of 50% or less when measured at 25°C according to JIS K 7136 (2000).SELECTED DRAWING: Figure 1
