Latest Patents

Ichiro Ishiyama's most recent patents demonstrate his commitment to enhancing the functionality of pressure-sensitive devices. One of his remarkable inventions is the "Pressure-sensitive resistor sensor having electrodes with reduced contact resistance deviation." The objective of this invention is to reduce the deviation in contact resistance variation among pressure-sensitive resistor sensors, which is crucial for consistent performance. This sensor design incorporates a pair of films—one film hosts multiple electrode portions extending in a specific direction, while the other film contains at least one electrode arranged transversely. By limiting contact points to the intersections of these electrodes, Ishiyama's innovation ensures minimal variation in contact resistance due to pressure shifts.

Another notable invention is the "Pressure sensitive transducer with pressure sensitive layer including high conductivity flaky carbon particles." This transducer features pressure-sensitive layers on resin films, which house both high and low conductivity carbon particles bound by a resin-system binder. When pressure is applied, the average distance between carbon particles decreases, facilitating a tunnel conduction phenomenon that lowers conductive resistance between electrodes. This results in a more refined pressure sensing capability.
