POWER IS THE PROBLEM - PIEZOELECTRIC ELEMENTS USAGE AS AN ENERGY SOURCE FOR SMART CLOTHING

摘要

The objective of this research was to verify the possibility of using alternative power sources for active elements of smart clothing (MEMS, sensors, LEDs, small medical facilities, etc.), or as a supporting source of energy for charging the main power source. The research aims to test the usage of flexible piezo elements attached to the garment as a generator of power. The mechanical energy of the bending and vibrating composite was transferred into electrical energy which is stored in user electronic circuit for later use. Due to the use of flexible piezoelectric composites, it was necessary to find and secure the optimum conditions for their usage to avoid any excessive load damage and also to be used up to their potential. It was also necessary to secure their position, so that these composites don't restrict user's movement.%S postupne sa zvyšujúcou integráciou elektronických členov (displejov, MEMS, čidiel, atď.) do tzv. Smart odevov, neustále narastajú požiadavky na ich napájanie. Toto napájanie je momentálne zabezpečované převážné z baterií, ktoré, ale vzhl'adom na malé rozmery a hlavne s ciel'om dosiahnutia čo najnižšej hmotnosti odevu, nemajú potrebnú kapacitu, pre dostatočnú výdrž v prostredí bez možnosti ich výměny, alebo bez dostupnej dobíjacej stanice. Tento článok sa zaoberá možnosťami napájania „Smart odevov" pomocou piezo kompozitov, ako doplnkového zdroja energie pre predíženie operačného času Smart odevov.
