Freestanding Micro-Supercapacitor With Interdigital Electrodes for Low-Power Electronic Systems

Highly Compressible Integrated Supercapacitor–Piezoresistance‐Sensor System with CNT–PDMS Sponge for Health Monitoring

“…Additionally, in order to power wearable devices and compose a self‐powered compressible system, energy storage devices, which could maintain performance under large strains, should be further discussed . Considering the fact that conventional solid‐state supercapacitors composed of carbon‐based materials, conducting polymers, and their composites are lack of compressibility, thus the appearance of the advanced supercapacitors called compressible supercapacitors (CSCs) paves the way for practical applications with long cycle life, great stability, and compatibility . The sponge‐like structure with high porosity is a remarkable configuration for CSC electrode, such as 3D graphene, aerogel, and carbon nanotubes (CNTs) .…”

Investigation of Device Dimensions on Electric Double Layer Microsupercapacitor Performance and Operating Mechanism

“…In this work we have studied the effect of design parameters for microsupercapacitor on the total capacitance of the device. The authors did not evaluate the effect of electrode width on total capacitance as it is clear that increase in electrode width would cause increase total capacitance due to increased surface area [19].…”

“…Interdigitated microsupercapacitors (MSC) on the other hand, have very fast charging/discharging, long life time and high power density and operating voltage. However, despite the clear superiority of interdigitated MSC over stacked geometry, as well as experimental evidence suggesting change in total capacitance of MSC by variation in device dimension [18], [19] there has been no thorough investigation to study this effect in depth to the best of our knowledge.…”

Laser fabrication of functional micro-supercapacitors

“…Concretely, photolithography is mainly suitable for the fabrication of 2D in-plane MCSs, in which the direct laser patterning and indirect template method are often carried out as the two major preparation strategies [105]. Herein, the direct laser processing is described as the directly carving of electrode films with photolithography [106,107], and then the microelectrode patterns (such as line, interdigital, concentric circles) are obtained by removing the excess active materials without the aid of other techniques [108]. For the indirect machining strategy, we classified it as the laser etching combined with other technologies to complete the microelectrode fabrication together [109].…”
