This study presents a new ac circuit element – the mutual capacitor, being a dual of the mutual inductor, which is also a new ac transformer.
For long life span AC module system, the electrolytic capacitor should be replaced to a film capacitor.
We demonstrate that an activated carbon (AC)-based electrochemical capacitor implementing aqueous lithium sulfate electrolyte in 7:3 vol:vol water/methanol mixture can operate down to −40 °C with good electrochemical performance.
The construction of an improved type of vibrating capacitor is described which is particularly suited for kinetic studies.
The data captured within this work presents the changes in capacitor properties from new, reaching to a point which the capacitor parameters have changed sufficiently, such that the capacitor can be considered to have failed.
Fluorinated activated carbon (F-AC) exhibits significantly improved electrochemical capacitive performance compared to raw activated carbon (R-AC).
This asymmetric aqueous AC//NaMnO 2 capacitor is promising for practical applications due to its low price, easy preparation of NaMnO 2 and friendliness to environment.
The designed 3.0-V class NiCo 2 O 4 /activated carbon (AC) hybrid capacitor exhibits a much superior performance to the theoretical 4.3-V class capacitor, owing to the effective control of Na-ion insertion/extraction reactions in the NiCo 2 O 4 electrode.
After prolonged floating of the AC/AC capacitor at 1.6 V and −40°C, the capacitance, equivalent series resistance and efficiency remain constant, demonstrating the absence of ageing related with side redox reactions at this temperature.

What is the surface energy of the electrode on a PCB?
5 answers
The surface energy of the electrode on a PCB can be influenced by various factors such as the electrode surface characteristics, contaminants present on the electrode surface, and the specific materials used in the electrode fabrication process. Research has shown that PCB-based electrodes can exhibit both organic and inorganic contaminants on their surfaces, which can impact their stability and repeatability in electrochemical sensing applications. Additionally, the fabrication of PCB-based electrodes for biosensors involves careful consideration of the electrode surface properties, as demonstrated in studies focusing on glucose biosensors and Ag/AgCl reference electrodes. These studies emphasize the importance of optimizing surface pre-treatment techniques to ensure the reliability and sensitivity of PCB-based electrochemical sensors for various applications, including clinical diagnostics and environmental monitoring.
Comparison types of moisture sensor in market?
5 answers
In the market, various types of moisture sensors are available for different applications. Capacitive sensors, as discussed inand, utilize impedance and are known for their durability, short response and recovery times, making them efficient for moisture measurement. Resistive sensors, commonly made of ceramic or organic polymer materials, are also prevalent but may have limitations in sensitivity compared to capacitive sensors. Additionally, piezoresistive sensors, highlighted in, offer fast response times and high sensitivity, suitable for detecting minute moisture levels. Furthermore, the use of dielectric elastomer sensors, as mentioned in, provides accurate moisture measurement by observing capacitance changes due to water content, offering flexibility and wearability. Each type of sensor has its unique strengths and applications in the diverse market of moisture sensing technologies.
