Pressure sensitive transducer with pressure sensitive layer including semi-conductive particles |
摘要 |
Pressure sensitive layers are disposed on respective resin films through electrodes to face each other, and include high conductivity flaky carbon particles and low conductivity amorphous-based carbon particles. The two kinds of carbon particles are bound together by a resin-system binder. Accordingly, when a pushing force is applied to the resin films, an average distance between the carbon particles is decreased to cause a tunnel conduction phenomenon, resulting in a decrease in conductive resistance between the electrodes. As a result, a pressure sensing property can be made gentle.
