Research status of strontium titanate
Currently, various electronic instruments, home audio and video equipment and microcomputer, etc., in order to prevent the equipment from the external power supply cord, transmission of noise and signal lines or air surge voltage, as well as the human body electrostatic factors lead to wrong operation or semiconductor devices are broken down, is the use of ZnO varistor for protection. However ZnO varistor is purely resistive element, although has good pressure sensitive features, but because of the small dielectric constant, [...]
