In this mini review, we summarize recent progress in smart supercapacitors with the functions of self‐healing, shape memory, electrochromism, and photodetection, including the design of electrode materials, the optimization of the configuration, and working mechanism.
Recently, a variety of smart supercapacitors have been successfully designed and fabricated by developing novel functional component materials and device configurations. In this review, we will present the recent developments in smart supercapacitors with self-healing, shape memory, electrochromism, and photodetection functions (Figure 1 ).
Therefore, if we want to carry out the research and design of multifunctional smart supercapacitors, it is very important to carry out horizontal research and design among various smart supercapacitors and establish the correlation link between each other.
This article presents an output capacitor-less low dropout regulator (LDO) that achieves fast transient response through a current compensation circuit. The push-pull structure improves the voltage swing rate at the gate of the pass device and enables the gate capacitor to quickly charge and discharge when switching between light and heavy loads.
The achievement of smart supercapacitors usually depends on the design of their configurations. However, conventional supercapacitors are mainly designed in button cells or spiral-wound configuration, which are too bulky and heavy to serve as smart energy storage devices.
Figure 3-2 shows the pre-charging and charging of the supercapacitor. As soon as the mains supply is present, the capacitor starts being pre-charged through the resistor and diode.

MEMS Tutorial: Pull-in voltage in electrostatic microactuators
Pull-in effect in plate capacitor. No equilibrium solutions are obtained above the pull-in voltage (red line). Above the pull-in displacement (green line), the actuator is unstable. With no applied voltage Equation (5) is simply ∂F ∂x = −k; a small positive movement δx result in negative restoring force ∂F ∂x δx= −k . Increasing the bias voltage U makes the stiffness less ...
