TOMSK, July 29 – RIA Tomsk. Student of Tomsk Polytechnic University (TPU) developed heating insoles for footwear which unlike all analogs will be charged when walking, work without wires, and temperature of insoles will be easily regulated, the press service of the higher education institution reported.
"The device is charged from body energy of a person thanks to piezo elements. Piezo elements react to foot pressure arising while a person takes a step. The device "removes" capacity appearing from pressure. <…> The innovation is convenient for polar explorers, tourists, shift workers", - it is told in the message.
It is specified that PowerInsole 2.0 created by the student of TPU Nikolay Volokhov is not the first in the world. However it is unique because piezo elements are used for its charging. Now the first experimental prototype of PowerInsole is created. The author of the project works on creation of the second, more advanced sample.
According to TPU, similar devices are produced abroad, however they have a last of shortcomings: they require replaceable accumulators (they aren't charged during walking), have wires connecting an insole and a battery, control panels. Besides, their temperature can't be regulated, and it is necessary to pull them out from footwear to recharge.
"The device is inexpensive and resource efficient, solves these problems. Batteries are placed in an insole, and it isn't necessary to wear them in a pocket. It will be possible to control the device with a special application in a smartphone", - is marked by the higher education institution.
It is added that it isn't necessary to derive an insole from footwear as widespread and popular standard of the inductive wireless charging of Qi is used there. And that energy, which collects in the device when walking, will be enough for charging of a cell phone.
