“…Recently, various devices have been developed for energy harvesting, such as the nanofluids ( He and Elazem, 2022 ), the spring-pendulum systems ( Wu et al, 2018 ; He et al, 2022a ), and the low-frequency vibration systems ( Zhang and Cai., 2012 ; He C.-H. et al, 2021 ; He et al, 2022b ). In addition to the abovementioned methods, the nanotechnology for solar energy harvesting ( Satharasinghe et al, 2020 ) is totally new and is quite promising.…”
