Recent efforts have been directed toward developing self-charging electrochemical energy storage devices capable of storing energy generated through body movements and vibrations [25, 26]. This paves the way for self-reliant, autonomous, and multifunctional systems.
Energy storage devices are the key component in ensuring the continuous and stable operation of microelectronic devices, thus playing a vital role in MESOC [197 – 200]. MESOCs are usually faced with dynamic energy demands to not only receive irregular energy inputs but also provide stable power output to the loads [201 – 204].
