Abstract: The present invention provides a transdermal sensor for detecting a concentration of a hypodermal target molecule, comprising: a substrate; a plurality of microneedles fixed on said substrate; a signal processing unit, which is electrically connected to said microneedles; and a power supply unit for providing the working power. The transdermal sensor of the present invention detects long-term, real-time concentration of a hypodermal target molecule for a doctor to evaluate a physiological status of an user with minimal invasive piercing and pain.

Abstract: A composite bio-ceramic dental implant and fabricating method thereof are disclosed. The composite bio-ceramic is sintered at a temperature between 1000 and 1800° C. using the nearly inert bio-ceramic powder and the active bio-ceramic powder or the completely resorbable bio-ceramic powder. The bioactive bio-ceramic material is dispersed in the inert bio-ceramic material. Therefore, the composite bio-ceramic has enough mechanical strength and good bioactivity for dental implant.

Abstract: An UHF RFID antenna for attached on any high conductive object is disclosed. The antenna radiation body has a first copper foil mounted thereon a backside surface of a FR4 glass fiber served as a ground plane, a second copper foil mounted thereon a front surface of the FR4 glass fiber as a main radiation plane. The main radiation plane contains two etched slits spaced each other. Each etched slit has a shape like a blade with a long handle. The two etched slits are mirror symmetry and a trench formed to connect the two etched slits for a RFID tag seated thereon so that There are short circuit microstrip and a feed-in microstrip are generated.
