Environmentally-Friendly Disposable Circuit and Battery System for Reducing Impact of E-Wastes solution ((CH3COO)2Mg) with air (O2). Since a voltage of 10V or higher was required to operate the organic circuit, 12 series-connected cells were fabricated. This battery could maintain the voltage of more than 10V at a current of 100μA for more than 3 hours.

The block diagram of the system is illustrated in Fig. 17.4.4. In this system, the developed battery acts as both power source and sensor. When the battery detects moisture, it generates electricity and power on the sensor circuit. Then, the sensor circuit transmits a detection signal with its own 3-bit ID assigned to each device. The signal is transmitted from a speaker with amplitude-shift keying (ASK) modulation by sound waves.
