Abstract
Behaviour of the radio and electric circuits can be changed if to add some mechanical interaction between their components to usual interactions. Then the circuits are to contain some piezoactive and tensosensitive components. In such circuits, for example, capacity of piezoelectric capacitors can become negative or infinite. Current through tensosensitive resistor fed by a.c. voltage contains the second or third harmonics. These examples show that some new branches of the radio and electric engineering can appear. They can become new consumers of ferroelectric and ferrite ceramics.
