Murata Manufacturing Co. is using high-transparency organic piezoelectric film for its two new devices, a remote control that works by bending and twisting, and a touch-pressure pad that connects to PCs. Murata will ship samples of both devices next year.

Murata says the film they are using has a high piezoelectric output constant; high transparency (light beam transmittance of 98% or higher according to the internal haze measurement) and most notably it is free from the “pyroelectric effect.”

Murata, in its press release announcing the devices, stresses what is special about its film. Conventional piezoelectric films are usually subject to a pyroelectric effect. The company says this is a drawback because they cannot detect bending and twisting vibrations separately from changes in temperature. Murata instead has developed a high-transparency piezoelectric film that is free from the pyroelectric effect. Murata developed the film through a joint research effort with Kansai University and Mitsui Chemicals.
