An improved multi-polar feedthrough assembly employs a particular metallic ferrule material for improved dimensional stability during initial fabrication and sustained hermetic operation. In one aspect, the disclosure relates to implantable medical devices (IMDs) including an IMD enclosure fabricated with grade 2 titanium and having a ferrule material fabricated with grade 4 titanium or grade 5 titanium. In one form, the multi-polar feedthrough assembly includes a filtered feedthrough array (e.g., employing capacitive filters coupled to the electrically conductive pins or serpentine conductors of the array). According to another aspect, the improved multi-polar feedthrough assembly incorporates additional pins, thus increasing the footprint of the assembly, and the additional pins provide analog electrical communication between operative circuitry inside an IMD and analog components external to the IMD.

A fabric including within its construction a first elongated electrical conductor crossed by a second elongated electrical conductor, the conductors being normally biased apart at a crossover point of said fibres with an air gap between them, whereby application of pressure in a direction substantially normal to a plane of the fabric causes the conductors to make contact. The fabric may be woven, knitted, non-woven or plaited. The fabric can be used as a pressure sensor, switch or other sensor.

The invention provides a biosensor and a method for manufacturing the biosensor. The biosensor comprises an insulating base plate, an electrode system, a reaction reagent and an insulating layer, wherein the insulating layer covers partial electrode system, and is formed with a closed region free from the insulating layer on the position of the reaction reagent; a closed boundary having no sharp angle is formed in the closed region enclosed by the insulating layer; the reaction reagent covers the closed region, and fails to exceed the closed boundary. Furthermore, the biosensor comprises an auxiliary diffusion electrode. The biosensor, through the closed boundary free from the sharp angle and the auxiliary diffusion electrode, can reduce an edge effect of the reagent, effectively distribute the reagent in a corresponding region of the electrode, effectively control the dosage of the reaction reagent, and reduce product cost. And the manufacturing method is simple.

The invention provides a biosensor. The biosensor comprises an insulating base plate and an electrode system positioned on the insulating base plate, wherein reagents capable of reacting with a detection sample are contained on the electrode system; the electrode system comprises a functional electrode for detection and auxiliary diffusion electrodes for controlling diffusion of the reagents; the functional electrode is positioned among the auxiliary diffusion electrodes. The auxiliary diffusion electrodes can overcome the effect of surface tension of the insulating base plate, so that the reagents can be smoothly and uniformly diffused on the electrode system and reaches to preset positions.
