Recently, massive data generated by wearable and flexible electronics set demand for efficient communication between sensors and terminals. High speed, low power consumption, and small hardware size are the key factors in data communication. As an example, we have demonstrated an integrated sensing system, including the power supply unit, sensors for collecting data, data processing (the filter and magnifier) and a communication module. The communication module is based on the low-power Bluetooth technology. Fast and reliable data collection is achieved, which is confirmed by the comparison with a wired processing module. We aim to expand our design to multi-sensing (such as strain, temperature, and pH) and physiological monitoring based on flexible and wearable electronics.
