Abstract
U ovom rada istražene su mogućnosti prikupljanja mehaničke energije iz okoline pomoću generatora zasnovanog na triboelektričnom efektu. Konstruiran je triboelektrični nanogenerator (TENG) s razmicanjem elektroda sastavljen od pleksiglasa, bakra i kaptona. U svrhu ocjene kvalitete TENG izvora mjereni su struja i napon praznog hoda te generirani naboj. Za mjerenje naboja razvijeno je pojačalo za mjerenje malih struja. Razvijena su dva testna sustava koja generiraju ponovljivu i kontroliranu mehaničku pobudu TENG-a potrebnu za mjerenje. Projektirana su i izrađena sklopovska rješenja za upravljanje energijom zasnovana na integriranim sklopovima LTC3588 i LTC3330 te rješenje izvedeno pomoću diskretnih komponenti. Razvijena je i programska podrška za bežični senzorski čvor temeljen na mikrokontroleru iz porodice nRF52. Čvor periodički mjeri ambijentalnu temperaturu i šalje je putem BLE komunikacijskog protokola. Razvijena je aplikacija za vizualizaciju mjerenja u programskom jeziku Python.
Abstract (english)
This thesis explores the possibilities of mechanical energy harvesting based on the triboelectric effect. The contact-separation mode triboelectric generator was developed and it consists of plexiglass, copper and kapton layers. In order to evaluate the performance of the TENG, the open circuit voltage and current were measured, as well as the generated electrical charge. Current amplifier for measuring small current was developed for measurement of generated charge. Two test rigs for repeatable and controlled mechanical excitation of the TENG were developed. Two power management circuits based on LTC3588 and LTC3330 integrated circuits were developed, along with additional power management circuit based on discrete components. Software for wireless sensor node based on microcontroller from nRF52 family was developed. Node periodically measures the ambient temperature and sends the measurement through the BLE communication protocol. Application for measurement visualization was developed in the Python programming language.
