Wearable wireless biopotential measurement device.
A light wearable wireless biopotential measurement device built up of commercial components is presented. The device utilizes 868 MHz ISM license free frequency band. Very low noise and good interference rejection is achieved using three electrode differential amplifier design and wireless signal transfer. The device has a possibility of calculating heart rate when ECG signal is measured, and transmitting only the heart rate value while conserving power.
