It's true. Necessity is the mother of all inventions.

In Japan, The Matrix Is Now Reality As Humans Are Used As Living Batteries ..........
..........So what is Japan's solution? A quite ingenious one: as Geek.com and ASR both report, Japan's Fujifilm has created organic printed sheet that harvests energy from body heat, or in other words, converts body heat to electricity. Finally, at least one key part of the Matrix "reality" is now fully operational - the use of human beings as batteries.
Specifically, Fujifilm Corp. and the National Institute of Advanced Industrial Science and Technology (AIST) have developed a resin sheet that generates electricity, utilizing the temperature difference between human body and the air.
The power-generating sheet developed by Fujifilm and AIST could be used to provide additional power for portable devices.
The sheet uses the thermoelectric effect, which generates a voltages due to the temperature difference between the surface of an object and its reverse side. The sheet is 0.4mm thick and soft. In a normal environment, the temperature of the air is lower than that of the human body or the surface of clothes. That temperature difference can be used to generate a steady flow of electricity.........
