Latest Patents

One of his latest innovations is a cardiac pacemaker that utilizes wireless transmission. This advanced pacemaker is designed to reduce weight and size, alleviating the burden on the wearer while ensuring safe signal transmission. The device features a main body equipped with at least two electrodes for detecting cardio-information, a control section for outputting pulses based on this information, and a transmitting section that modulates and transmits these pulses. Additionally, the pacemaker includes a pacing electrode portion with a receiving section that stimulates electrodes activated by the received pulses.

Another notable patent is an ultrasonic probe that incorporates a backing material layer of uneven thickness. This probe consists of a piezoelectric material layer with electrodes on both surfaces for voltage application. The backing material, which has a lower acoustic impedance than the piezoelectric layer, is interposed with an acoustic reflecting material layer that varies in thickness. This design allows the ultrasonic probe to effectively transmit and receive ultrasonic waves at its resonance frequencies.
