| Research Abstract |
By eliminating the battery from electronic paper terminal using the wireless power transmission technology, this study aims to develop thinner, more lightweight and lower cost electronic paper device.
Because the transmitting distance of generally used electromagnetic induction is limited to a few cm or less, we employed the wave received wireless power transmission technology which can receive the power even in the distance 1m or more.
We developed the technology which can drive the electronic paper less than 10 mW by combining the driving and communicating ICs into one chip and by improving the driving method for lower power consumption of the electronic paper terminals.Further, to transmit this power to the electronic paper terminal in 1 m away, we have developed a unilateral directional flat flexible antenna and rectifier circuit with high efficiency.
