Title:
WEARABLE SENSOR TERMINAL
Document Type and Number:
WIPO Patent Application WO/2022/269859
Kind Code:
A1
Abstract:
This wearable sensor terminal is provided with: a secondary battery (111); a charging IC (110) for, when the voltage of the secondary battery (111) is equal to or more than a threshold voltage, rapidly charging the secondary battery (111); a wireless communication module (114); an LDO regulator (113) for converting the voltage of the secondary battery (111) and supplying the converted voltage to the wireless communication module (114); and a protection circuit (116) for, when the voltage of the secondary battery (111) is less than the threshold voltage at the time of charging, stopping supply of power-supply voltage from the LDO regulator (113) to the wireless communication module (114).
