    摘要： An artificial sphincter system having: (1) a hollow object, which has the ability of contraction and expansion; (2) a shape memory alloy (SMA), which is connected with the hollow object, changes its shape to imitate the motion of human muscle by applying different electric current; (3) an electric power to provide different amounts of electric current to the shape memory alloy and let it contract or expand to control the motion of the hollow object to imitate the motion of human muscle; and (4) a photo resistor added between the electric power and the shape memory alloy, which senses the brightness of surrounding light and controls A/D (analog-to-digital) values of the electric power to cause different conditions of contraction and expansion of each part of the shape memory alloy.

    摘要： The invention discloses a method and apparatus to control the shaping change of Shape-Memory-Alloy (SMA). The piece-wised current drain control device is designed to independently deliver current to stimulate sectional SMA but not the entire one. The invention is also successfully implemented on an automatic light sensitive aperture control device to simulate the light response of a pupil. The control technique can extend the application potential of SMA toward precise actuation, aeronautical applications, surgical tools, or biomedical applications such as artificial organ or muscles.

    摘要： Disclosed herein is a method for treating a brain disease in which focused ultrasound and magnetic targeting are applied to a subject in need of such treatment, so that therapeutic agent-magnetic nanoparticle composites are directed across the blood-brain barrier to a designated locus inside the brain of the subject. Each of the composites includes a magnetic nanoparticle that is formed of an iron-based core and a shell encapsulating the iron-based core, and a therapeutic agent that is bound to the shell of the magnetic nanoparticle. The magnetic nanoparticle has a size ranging from 5 to 200 nm. The iron-based core has a crystalline structure that imparts the composites with a sufficiently high magnetization, thereby enhancing magnetic targeting of the composites to the designated locus inside the brain of the subject. The magnetic targeting treatment is conducted via a magnet providing a magnetic flux density not less than 0.18 T.
