Abstract The droplet‐based electricity generator (DEG) has facilitated efficient droplet energy harvesting, yet diversifying its applications necessitates the incorporation of various to DEG. This study first proposes a methodology for advancing DEG by substituting conventional metallic electrode with electrically conductive water (WE), which is spontaneously generated during operation operating liquid. Due inherent and fluidic nature water, introduction WE maintains electrical output performance while imparting functionalities such as high transparency flexibility. So, resultant applied (WE‐DEG) exhibits optical transmittance (≈99%) retains electricity‐generating capability under varying deformations, including bending stretching. innovation expands versatility DEG, especially, sun‐raindrop dual‐mode harvester demonstrated hybridizing WE‐DEG photovoltaic (PV) cell. hybridization effectively addresses weather‐dependent limitations in each enhances temperature‐induced inefficiencies typically observed PV cells, thereby enhancing overall efficiency. will be poised catalyze new developments research, paving way broader applicability enhanced efficiency harvesting technologies.

As an emerging technology to convert environmental high‐entropy energy into electrical energy, triboelectric nanogenerator (TENG) has great demands for further enhancing the service lifetime and output performance in practical applications. Here, ultra‐robust high‐performance rotational (R‐TENG) by bearing charge pumping is proposed. The R‐TENG composes of a TENG (P‐TENG), (O‐TENG), voltage‐multiplying circuit (VMC), buffer capacitor. P‐TENG designed with freestanding mode based on rolling ball bearing, which can also act as rotating mechanical harvester. low from accumulated pumped non‐contact O‐TENG, simultaneously realize ultralow wear high performance. matched instantaneous power increased 32 times under 300 r/min. Furthermore, transferring remain 95% during 15 days (6.4 × 10 6 cycles) continuous operation. This work presents realizable method enhance durability TENG, would facilitate applications harvesting distributed ambient micro energy.
