“…135 Aer this architecture was proposed, various hybrid energy harvesters were suggested and demonstrated using acoustic waves and pressure for the piezoelectric effect, which were based on PVDF TENG-based multi-type energy harvesters have also received great attention because of their high output power and easy hybridization with other energy harvesters. [139][140][141][142][143][144] In 2013, Yang et al demonstrated a hybrid energy harvester based on the triboelectric effect and the PV effect for the rst time. Micropyramid Si solar cells were fabricated with a protective layer consisting of a thin lm of polydimethylsiloxane (PDMS) nanowires, which not only worked as a protective layer, but also as a triboelectric layer for harvesting mechanical energy ( Fig.…”

Currently, integration of energy harvesting and storage devices is considered to be one of the most important energy-related technologies due to the possibility of replacing batteries or at least extending the lifetime of a battery. This review aims to describe current progress in the various types of energy harvesters, hybrid energy harvesters, including multi-type energy harvesters with coupling of multiple energy sources, and hybridization of energy harvesters and energy storage devices for self-powered electronics. We summarize research on recent energy harvesters based on the piezoelectric, triboelectric, pyroelectric, thermoelectric, and photovoltaic effects. We also cover hybrid cell technologies to simultaneously generate electricity using multiple types of environmental energy, such as mechanical, thermal, and solar energy. Energy harvesters based on the coupling of multiple energy sources exhibit enhancement of power generation performance with synergetic effects. Finally, integration of energy harvesters and energy storage devices is introduced. In particular, self-charging power cells provide an innovative approach to the direct conversion of mechanical energy into electrochemical energy to decrease energy conversion loss.

“…Recently, triboelectric nanogenerator (TENG) based on contact-electrification [13][14][15] was developed to harvest water energy from various energy form, such as ocean waves [16], flowing water [17,18] and raindrops [16,19,20]. Essentially, TENGs [8,9] harvest ambient energy by means of the contact and separation of two materials.…”

“…On the other hand, water-solid interaction also causes triboelectricity with the formation of an electrical double layer (EDL) [28][29][30][31][32]. Using water as a charging material directly, a TENG can harvest water energy (water-TENG) based on a fairly simple structure consisting of one electrode and one solid material [19,20]. With a transparent polymer surface and a single electrode, the water-TENG can successfully cause light to penetrate to a solar cell [20].…”

“…Electrocoalescence and breakups of drops are an important research subject in climate science [40,41] as well as in the dehydration process of crude oil [42,43]. Liquid contact electrification charging of drops can be employed in portable energy harvesting devices [44][45][46][47][48][49][50]. Understanding of the charged droplet behavior under electric field is critical in electrospray mass spectrometry [51][52][53][54] and electrohydrodynamic (EHD) printing technology [55,56].…”
