[CEATEC 2011] Fujitsu knows that renewable energy is the way to go, which is why the Japanese company is working on different ways to deliver energy to power devices without sucking up more juice from the grid. In this matter, Fujitsu intends to come up with a system that can harvest energy from human activity or the environment that can be converted for use in IT and electrical equipment around. Imagine wearing a prototype like what you see above around your wrist – every little bit of kinectic energy, heat and light sources will generate microwatts of juice that while isn’t enough to keep your iPhone’s battery well stocked always, it is enough to power a sensor that can “sense” and “send” information to a wireless or local network.
Basically, future sensors in devices might no longer need to obtain their juice from a battery, which will clearly increase the efficiency of devices. After all, who doesn’t want to enjoy long lasting devices? Not only do you have less hassle when you travel since there is less stuff to carry around, you can also do your bit in reducing used batteries and parts in landfills.
