I want to know what is the material that has a moisture and electrical properties response ?

Do I have an idea to create an electrical device that is related to moisture using some materials that are responsive to moisture and electrical properties

Please be more specific. Are you trying to make a moisture sensor? Almost all electrical devices stop working if you dunk them in water. We can't guess what you mean.

OK, the word you need is hygometer. There are very many types. Electric ones include
  • Capacitive
  • Resistive
  • Thermal
  • Gravimetric
  • Optical
