Electromechanical coupling of biological tissues
From quantum devices to pioneering medical diagnostic technologies
We aim to contribute to non-invasive biological sensing, material characterization, and quantum technology through the development of novel ultrasound and terahertz wave imaging systems and the creation of innovative devices utilizing quantum phenomena. Our research themes are cross-disciplinary and challenging. We are looking forward to working with curious students to create technologies that contribute to society.
Visualizing Electricity and Magnetism with Ultrasound: ASEM Technology
Ultrasound is widely used in medical diagnostics and industrial testing. Its greatest feature is that it can gently image the contents of humans and concrete, which are invisible to the eye, without destroying them from the outside. Conventional ultrasonic echo methods diagnose internal defects and foreign bodies, but we have developed a technology that can image electrical and magnetic properties using ultrasonic waves (Acoustically Induced Electromagnetic Method: ASEM). This new technology is expected to provide imaging information on degeneration and deterioration of musculoskeletal systems such as bones, tendons, and ligaments, fibrosis of organs associated with chronic diseases, and degeneration and residual stress in various materials, which cannot be obtained with conventional measurement techniques such as ultrasound echo, MRI, and CT. We are developing ASEM as a new modality to contribute to society through new medical and healthcare devices that extend healthy life expectancy, devices and services that support athletes' prevention and healing decisions, and inspection technologies that are useful for social infrastructure maintenance and quality control of industrial products.
Photoelectric device development
We are working on the ultimate control of electrons and light using advanced semiconductor technology. One of our targets is terahertz light, which lies in the band between radio waves and optical waves. Terahertz light refers to electromagnetic waves in the terahertz frequency range, situated between radio waves and light. It holds great potential for applications ranging from ultra-high-speed information communication to bio-sensing and medical diagnostics. However, this remains an unexplored field where conventional electronics and photonics alone are insufficient. We conduct research on fundamental physics utilizing semiconductor quantum structures, including single THz photon detection, THz amplification, and electron-phonon strong coupling (resonant polaron). Furthermore, we are exploring novel mechanisms that could bring transformative advancements not only in electronics and photonics but also in the field of information science, such as terahertz photonic circuits and optically programmable CMOS.
