Piezoelectric-driven self-charging energy storage systems (PS-ESS) are an emerging integrated energy technology that combines energy conversion and energy storage in a single unit without the need for external circuits for charging, and are therefore widely deployed in wearable and implantable devices.
However, conventional energy conversion and storage devices rely on two separate components: active harvesting elements and a storage medium, which are connected by additional technical support, such as integrated circuits. These devices are highly dependent on circuit design and rectification technology in practical applications.
While conventional energy storage devices, such as supercapacitors, lithium-ion batteries, lithium-ion capacitors, sodium-ion batteries, generally possess a charging voltage window exceeding 1 V. A wider charging voltage window is advantageous for increasing both the energy density and practical application value of the device.
