New technique for generating electricity from mechanical vibrations By Richard Moss November 12, 2014 Natural vibrations caused by two surfaces with different work functions repelling and attracting each other can be used to generate electricity (Image: VTT) Electrical energy is normally generated through heat, motion, nuclear transformation, or chemical reactions, but now scientists at VTT Technical Research Center of Finland have devised a new method that involves mechanical vibrations. They figured out how to “harvest” the vibrational energy that occurs naturally when two surfaces with different work functions are connected via electrodes, and this energy could potentially be used to power wearables and other low-power electronics. A work function is a property of the surface of a material that is defined as the difference between the energy of an electron at rest and the minimum thermodynamic work (another form of energy) that is required to remove said electron from the material. It’s often applied in photoelectric devices and cathode-ray tubes, and is sometimes guarded against in electronic circuits involving different metals, but it had not before been used in vibration energy harvesting. The VTT scientists created a parallel-plate capacitor with copper and aluminum that was hooked up to an external circuit. The plates’ respective work functions provided the initial one volt charge as electrons fled from one surface to the other. Different el...

Today we will be taking a looking at one of Azio's newest gaming keyboards on the market, the Azio Levetron Mech5 mechanical keyboard. The Mech5 is Azio's most innovative mainstream mechanical gaming keyboard available today. As of the last few years, mechanical keyboards have gotten really popular and we are seeing many competitors releasing their own designs in an attempt to capitalize on this new craze. Azio designed the Levetron Mech5 to be completely modular, so fit and finish will be an important aspect to keep in mind; however, let's not forget that functionality is just as important when it comes to mechanical gaming keyboards. So today we are going to put the Azio Levetron Mech5 to the test and see how it stacks up.
