My interests in biomechanical energy sprouted in childhood. In many cartoons, I always saw a bulb lit up on top of someone’s head when this character came up with an idea. At that time, I believed that something must change inside our body when we are thinking. A few years later, a program on Discovery showed that when people are thinking, the energy consumed by the brain equals the energy powering a 5w bulb. Exciting! Then I wish I could make a desk lamp which will be lighter when I thinking harder and become deemer when I tired.

I found this paper here: http://www.sciencemag.org/content/319/5864/807.full
When reading this paper, I came up with an idea: Generating Electricity During Useing The Mouse
