  • Publication number: 20120283695
    Abstract: A transdermal drug delivery patch and a method of controlling the drug release of the transdermal drug delivery patch by near-IR are disclosed. The transdermal drug delivery patch comprises a substrate, carriers and drugs. The drugs are encapsulated in the carriers, and the carriers having the drugs are disposed on a surface of the substrate. The carriers are formed of biodegradable polymers, and nano-particles with a photothermal conversion effect are loaded in the carrier. When the carriers are punctured into the skin and the nano-particles in the carrier absorb the near-IR, the near-IR is converted into heat by the nano-particles to melt the carrier and thus releasing the drugs encapsulated in the carrier into the skin. Accordingly, the speed of releasing the drugs encapsulated in the carrier can be controlled accurately by the near-IR.

  • Publication number: 20120132242
    Abstract: A thermoelectric generator apparatus disposed on a high-temperature surface of an object (as a heat source), at least includes a heat concentrator, a thermoelectric module and a cold-side heat sink. The heat concentrator has a top surface and a bottom surface contacting a high-temperature surface of the object, and an area of the bottom surface is smaller than that of the high-temperature surface. The thermoelectric module is disposed on the top surface of the heat concentrator. The cold-side heat sink is disposed on the thermoelectric module. Heat generated by the heat source is concentrated on the heat concentrator and flows to the hot side of the thermoelectric module for increasing the heat flux (Q?) passing the thermoelectric module and the hot side temperature of the thermoelectric module. Consequently, the thermoelectric conversion efficiency (?) is improved, and the power generation of the thermoelectric module is increased.
