Title:
ELECTRONIC APPARATUS, BED SENSOR, AND SENSOR FOR SHELF
Document Type and Number:
WIPO Patent Application WO/2023/176847
Kind Code:
A1
Abstract:
An electronic apparatus (1) comprises a sensor (10), which is a piezoelectric element-type sensor that outputs a voltage corresponding to applied pressure, and a first detection circuit (20) that detects continuous pressure applied to the sensor (10) from the output voltage of the sensor (10). The first detection circuit (20) includes a capacitor (21) connected in parallel to the sensor (10), and a high input impedance circuit (22) connected in series to the sensor (10).
