Outline of Final Research Achievements

A new energy harvesting with low installation cost is proposed to enable stable power supply to battery-less wireless sensor nodes for energy management systems. Two electrodes (copper tapes) are attached on the insulating cover of two-wire power cords and the leakage electric-field energy is harvested by the capacitive coupling between the electrodes and the core wires. The proposed energy harvesting does not require an additional ground connection and the current in the power cords. 3-4V, 1.4uW is harvested with 20-cm electrodes from 100-V AC power supply. Temperature and illuminance sensor nodes with the proposed energy harvesting and ZigBee modules for the building energy management system are demonstrated. Both the temperature and illuminance are measured and transmitted to a wireless receiver within a 100-m radius every 250s.
