The converted or collected energy must be stored to provide a stable power supply for wearable electronics.
Benefiting from rapid charge-discharge rate, high power density, stability and safety, MSCs have become
promising candidates for microscale energy storage devices . The ion adsorption or surface redox reaction
[123]
at the interface between electrodes and electrolytes implemented the energy storage process. Song et al.
reported transparent, stretchable, and soft in-plane MSCs based on porous LIG electrodes [Figure 13G] .

The fabricated device showcased remarkable stretchability up to 400% and long-term stability (1,000 times).
