'흔들어서 충전해요' 노키아 운동에너지 충전 특허 출원

스마트폰 경쟁이 치열해지면서 휴대폰 파워가 올라가고 있지만 반대급부로
배터리 소모도 빨라지고 있는데 태양열충전과 같은 보조 수단이 등장하고 있지만
아직까지는 만족스럽지 못한 현실

이에 노키아에서 운동에너지를 이용한 충전법을 제안을 했는데 이미 크랭크축을 이용한
액서사리 충전기가 나와있는 상황에서 어떤식으로 진행이 될지 재미있게 지켜볼만할 듯.

Piezoelectric Kinetic Energy Harvester
A battery for an electronic device is contained within a first frame that is coupled to a second frame by one or more piezoelectric elements. The second frame is coupled to a device chassis by one or more additional piezoelectric elements. In response to translation and/or rotation of the electronic device, portions of forces induced by the battery mass are transferred to the piezoelectric elements. Electrical energy output by these piezoelectric elements is received in a power controller and can be applied to the battery. Additional device components can also be contained within the first frame so as to increase the total mass that induces forces applied to the piezoelectric elements.

Nokia files patent for kinetically-charging mobile phone battery

by Devin Coldewey on March 8, 2010

Question: can you file a patent for something that’s existed for a long time? I guess the question is of implementation. While self-winding watches and shake-to-charge flashlights already harvest kinetic energy to store and later discharge, I suppose they do it in a different way than this proposed system from Nokia. Not sure I trust something sliding back and forth in my phone, either. And wouldn’t that necessitate a bunch of empty space that could be taken up with, I don’t know, a bigger battery?

Well, I shouldn’t carp at a perfectly practical idea. How often have you been stuck somewhere with a low battery, and no outlet in sight? Shake your phone a few hundred times and you’ve gained… a couple minutes of power. And a lot of weird stares.
