  • Publication number: 20200121959
    Abstract: Disclosed herein is a non-invasive treatment system using intermedium, and an exemplary treatment system is configured to output high-intensity focused ultrasound to remove bone tissue, inject an acoustically-transparent medium into a part where the bone tissue is removed to generate an intermedium, and output therapeutic ultrasound that passes through the intermedium. Accordingly, the bone tissue is removed in a non-invasive way using high-intensity focused ultrasound, and the intermedium is generated at the bone tissue removed site, to increase the penetration of therapeutic ultrasound or generate ultrasound itself, thereby improving an ultrasound treatment effect while minimizing the side effect (for example, infection of dura mater) of invasive surgery methods.

  • Publication number: 20190322524
    Abstract: A membrane device includes a trench substrate having trenches and a membrane having wrinkles. The membrane is not bonded to the trenches of the trench substrate but is bonded to the surface of the trench substrate in the shoulders of the trenches. Hills and valleys are alternately arranged in the membrane along the trenches. The membrane device can be used in various applications (for example, sensors) based on variations in the electrical properties of the membrane caused by a change in the shape of the wrinkles (a change in the strain) of the membrane in response to a change in the internal or external environment of the trenches.
