Engineers have developed a generator with no moving parts, embedded in the sole

Engineers from the University of Wisconsin-Madison have developed a system electricity generation fits into the sole of the shoe. In this case, unlike similar projects, the system has no mechanical moving parts. Electricity generated by walking are encouraged to use for charging gadgets.

This charger is well suited for military applications, the tourists and the inhabitants of remote regions with problems with a constant power supply.

According to the calculations of one of the engineers, Tom KRUPENKIN, power devices in one shoe can reach 10 watts - that is, in the amount of turn 20 watts. According to the scientist, this energy normally dissipated as heat, while even 10% of this energy is enough to charge a typical smartphone.

Technology works on the principle of "reverse electrowetting" - a process that KRUPENKIN paired with Ashley Taylor opened in 2011 it was searching for converting mechanical energy into electrical energy for the collection of human motion energy.



The apparatus consists of two flat plates between which the conductive fluid is circulated. The bottom plate has done the microscopic holes, and it is connected to the electrode insulation. Pressurized fluid is fed through the microperforations gas forming bubbles which then collapse into larger bubbles. This iterative process that takes place at high speed, the liquid moves on a path that leads to the generation of electric current due to the электросмачиванию.

The power of the experimental setup is 10 watts per square meter. The researchers argue that this power can be increased by 1000 times. According to them, such a bubble technology shows the largest energy density per unit area among the devices for converting mechanical energy into electrical energy.

By embedding such a system boots, it is possible to store energy in a battery and then charge the device. Or, as suggested by the engineers, embedded in the sole and more WiFi-Repeater, which will reduce the smartphone power consumption by reducing the power required to transmit the signal.
