The article gives an overview of the problems and solutions related to energy harvesting systems used for power supply of low power electronics systems. Power density is the main parameter describing the efficiency of energy harvesting systems. Piezoelectric energy harvesting systems demonstrate a high value of power density, and therefore the article presents an overview of piezoelectric energy harvesting systems and their components. Also, a summary of the terms that affect the efficiency of piezoelectric energy harvesting systems has been presented. Straipsnyje apžvelgiamos problemos ir sprendimai, susiję su elektrinės energijos tiekimu mažos galios elektronikos sistemoms, taikant energijos surinkimo iš aplinkos technologijas. Vienas iš pagrindinių energijos surinkimo sistemas apibūdinančių parametrų yra galios tankis. Pjezoelektrinė energijos surinkimo technologija pasižymi vienu iš didžiausių galios tankiu, todėl straipsnyje išsamiai nagrinėjami pjezoelektriniai kinetinės energijos keitikliai, apžvelgiamos keitiklių konstrukcijos, jų sudedamosios dalys, išskiriamos technologinės sąlygos, darančios įtaką keitiklių efektyvumui.

In photoelectric micro-power supply integrated on chip, the conversion efficiency of solar cell was lower compared with canonical solar cell. In order to improve the conversion efficiency of the solar cell, three technologies (fabricating back surface field, fabricating surfaces texture and reflector) were adopted in integrated process of photoelectric micro-power supply on chip. The relevant theory of the three technologies was introduced. The optimum schedule of the photoelectric micro-power supply integrated on SOI wafer was proposed. The conversion efficiency of solar cells was analyzed by simulation tools (PC1D). The results prove the conversion efficiency of solar cells was improved from 9. 34% to 13.3%.
