Performance Analysis of SDT Shielded Piezo (TE1000288-0) And LDT1-028K Piezoelectric Transducers in Energy Harvesting From Chiller Plant

In recent years, harvesting energy from noise pollution has gained momentum as a promising field of research. Industrial activities, such as chiller operations, manufacturing equipment, and construction, naturally generate significant noise, which can be difficult to isolate from the surrounding environment. However, there is a lack of research on piezoelectric-based noise energy harvesting. Further investigations are needed to optimize system design for higher energy conversion efficiency. This paper presents the performance analysis of piezoelectric transducers for harvesting energy from noise generated at a chiller plant. The sound level on the piezoelectric is experimental at range of 82–100 dB, corresponding to the zones classified in the chiller plant noise. In this study, two types of piezoelectric transducers, LDT1-028K and SDT-TE1000288-0, were investigated as energy harvesters. Both transducers are based on polyvinylidene fluoride (PVDF) material. The experimental setup included a noise harvester system consisting of a capacitor and rectifier. The results indicate LDT1-028K has superior energy harvesting efficiency in comparison to the SDT-TE1000288-0 piezo sensor where it is accomplished maximum power response performance of 0.0258 mV at 95 dB. The results show that noise pollution from sources such as chiller operations, industrial machinery, and construction activities can be converted into usable electrical energy. By harnessing and utilizing unregulated noise, this approach offers a promising solution for powering compact electronic devices, including mobile phones, monitoring sensors, and industrial appliances.
