Experimental Study on Electric Signal Response of Liquid in Flexible Tube Under Deformation

Abstract

Steaming potential is an electrical phenomenon caused by the flow of liquid along a solid surface. In order to adapt to the more complex environment and meet the higher requirements, the electrochemical response of flexible tube under external load may lay a foundation for the research of new sensor. Reasonable design of flexible tube and electrode structure, built a suitable measurement system to measure its electrical response. The results show that the frequency of the electrical signal fluctuates with the load fluctuation, and it has the characteristics of frequency doubling at higher values.
