Abstract
U ovome diplomskom radu opisana je tehnologija prikupljanja niskorazinske energije iz okoliša, kao i koncepti pretvorbe prikupljene energije u električnu energiju. Ovaj rad opisuje šest koncepata, ali stavlja naglasak na piezoelektrični koncept odnosno piezoelektrične pretvarače za primjene u nosivim tehnologijama. Opisani su različiti sustavi za prikupljanje niskorazinske energije iz okoliša za neke primjere nosivih tehnologija. Rad se sastoji i od eksperimentalnog dijela gdje se ispituju optimizirani piezoelektrični pretvarači. Prije eksperimentalnog dijela opisani su utjecaji različitih čimbenika kao što je geometrija konzolnog piezoelektričnog pretvarača o kojoj jako ovisi izlazni napon. Nakon analiziranih dostupnih znanstvenih radova, na eksperimentalnom postavu provode se eksperimentalna ispitivanja optimiziranih oblika piezoelektričnih pretvarača podvrgnutih harmonijskoj uzbudi u svrhu dobivanja optimalnih uvjeta rada.
Abstract (english)
This thesis describes the technology of collecting low-level energy from the environment, as well as the concepts of converting the collected energy into electricity. This paper describes six concepts but emphasizes the piezoelectric concept that is piezoelectric transducers for applications in wearable technologies. Different systems for collecting low-level energy from the environment are described for some examples of wearable technologies. The paper also consists of an experimental part where optimized piezoelectric transducers are tested. Prior to the experimental part, the influences of various factors such as the geometry of the cantilever piezoelectric transducer on which the output voltage strongly depends are described. After analyzing the available scientific papers, experimental tests of optimized shapes of piezoelectric transducers subjected to harmonic excitation are performed on the experimental setup in order to obtain optimal operating conditions.
