Supercapacitors Explained: How EDLC, Pseudo, and Hybrid Capacitors Store Power14 July 2026
Supercapacitors, also known as electrochemical capacitors, electric double-layer capacitors, gold capacitors, and farad capacitors, are developed between the 1970s and 1980s, which is an electrochemical element that uses polarized electrolytes to store energy. The supercapacitor is different from the traditional chemical power supply. It is a power supply with special performance between the traditional capacitor and battery, which mainly relies on the electric double layer and redox pseudo capacitor charge to store electrical energy. However, no chemical reaction occurs during the energy storage process. This energy storage process is reversible, for which supercapacitors can be repeatedly charged and discharged hundreds of thousands of times.
An Overview of JFET19 August 2020
JFET is a Junction field-effect transistor. Regular transistor is a current-controlled device that requires biasing power, while JFET is a voltage-controlled device. The JFET is an active electronic component that is one of the electronics industry's workhorses that offers a reasonable compromise between cost and efficiency.
An Overview of Digital Signal Processor31 October 2025
A digital signal processor (DSP) is a processor composed of large-scale integrated circuit chips to complete digital signal processing tasks. Digital signal processing is the theory and technology of representing and digitally processing signals. Digital signal processing and analog signal processing are a subset of signal processing.

What are Types and Application of Gas Sensors?18 November 2025
The gas sensor is the core of the gas detection system and is usually installed in the detection head. Essentially, a gas sensor is a converter that converts a certain gas volume fraction into a corresponding electrical signal. The probe uses the gas sensor to adjust the gas sample, which usually includes filtering out impurities and interfering gases, drying or refrigeration treatment, sample pump, and even chemical treatment of the sample, so that the chemical sensor can make faster measurements. In the following, we’ll mainly discuss the properties, typical types and application fields of gas sensors.
