Biosignal Sensor as Charging Electrode in Vehicle Healthcare Device

Solution Overview

Problem

Existing healthcare devices for vehicles require a separate charging pin, which negatively affects their aesthetic appearance and increases costs and size, as they need a hole for pogo pin connection during charging.

Innovation Solution

The biosignal measuring sensor is used as a charging electrode, eliminating the need for a separate charging pin by connecting the sensor device battery to an external pogo pin through the biosignal measuring sensor electrodes, allowing the same sensors to measure biosignals and charge the device.
