Flexible force or pressure sensor array using semiconductor strain gauge, fabrication method thereof and measurement method thereof

The force or pressure sensor array of the present invention effectively has both flexibility and elasticity. Since the substrate itself is a kind of a polymer material, the substrate can be bent or expanded. Although silicon, which is a material of the semiconductor strain gauge, is easily broken and solid, mechanical flexibility can be secured if it is fabricated extremely thin. To this end, particularly, disclosed is a flexible force or pressure sensor array using semiconductor strain gauges 110, the sensor array comprising: a substrate 10 including: the semiconductor strain gauges 110 in which a plurality of elements formed in a certain array pattern is deformed by force or pressure, a pair of polymer film layers 120 and 130 having film surfaces contacted facing each other and containing the semiconductor strain gauge 110 between the film surfaces contacted with each other, and a pair of signal line layers formed on top and bottom surfaces of an insulating layer using either of the pair of polymer film layers 120 and 130 as the insulating layer and connected to the elements 111 of the array pattern to form electrodes, for fetching deformation signals outputted due to deformation of the elements 111 to outside; and a pair of elastomer layers 20 and 30 formed on both sides of the substrate 10 to contain the substrate 10 inside.

Electric connector for twisted pair cable using resin solder and a method of connecting electric wire to the electric connector

The objectives of the present invention include to connect a twisted pair cable to the electric connector without undoing the twist of the end of the twisted pair cable, to accurately keep the twist of the twisted pair cable up to the end thereof, to make the twisted pair cable fully exhibit its noise cancellation effect, and to maximize impedance matching. The electric connector for twisted pair cable using resin solder according to the present invention comprises a pair of electric contacts having the first connecting part, which fits with the counterpart connector, and the second connecting part, to which the conductor of the electric wire is connected, and an insulating member, which insulates and holds these electric contacts. In each of the electric contacts, at least a part of the second connecting part, to which the conductor of the electric wire is connected, is made of a lead-free ultrahigh-conductive plastic being a conductive resin composite.

Microsphere type embolic agent and preparation technology thereof

The invention provides a microsphere embolic agent, which is an elastic microsphere formed by the crosslink polymer of the functionalized macromolecules with the biocompatibility, and the particle size of the microsphere ranges from 1 Mum to 1500 Mum. The preparing technology includes the steps as follows: in a covalent link, linking a crosslinkable micromolecules with an acrylic acid structure on the polyvinyl alcohol, polyethylene glycol or polysaccharide macromolecules, forming the functionalized macromolecules; after that, the functionalized macromolecules and the monomer of the 2- acrylamide-2-methyl propanesulfonic acid undertakes opposite suspension polymerization, obtaining the crosslink polymeric microsphere embolic agent. The embolic agent has comparatively large retractility and elasticity, whose particle size is controllable and has perfect dispersiveness; moreover, the raw material is non-toxic and at the same time has good biocompatibility and stability. The preparing technology is a real chemosynthesis technology, whose material and preparing process does not produce any virus pollution, according with various requirements of the international embolic agent, which can replace various import and domestic expensive embolic agent products and is extensively applicable to various surgeries in the interventional radiology field.

Floating seal assembly for a trocar

A seal assembly used in combination with a trocar assembly and disposed and structured to establish sealing engagement with the exterior surface of medical instrument introduced into the trocar assembly so as to maintain adequate insufflation pressure within a body cavity accessed by the trocar assembly. The seal assembly includes a seal member unconnected to and freely moveable, at least laterally, within a seal chamber of the trocar assembly. The seal member and the seal chamber are cooperatively dimensioned to maintain one or more outer peripheral surfaces of the seal member in surrounding, sealing relation to one or both of the inlet and outlet ports of the seal chamber thereby eliminating or reducing the escape of insuflation gas through the trocar assembly when an instrument is present therein.
