    摘要: A method of forming a polymer-based microfluidic system platform using network building blocks selected from a set of interconnectable network building blocks, such as wire, pins, blocks, and interconnects. The selected building blocks are interconnectably assembled and fixedly positioned in precise positions in a mold cavity of a mold frame to construct a three-dimensional model construction of a microfluidic flow path network preferably having meso-scale dimensions. A hardenable liquid, such as poly (dimethylsiloxane) is then introduced into the mold cavity and hardened to form a platform structure as well as to mold the microfluidic flow path network having channels, reservoirs and ports. Pre-fabricated elbows, T's and other joints are used to interconnect various building block elements together. After hardening the liquid the building blocks are removed from the platform structure to make available the channels, cavities and ports within the platform structure. Microdevices may be embedded within the cast polymer-based platform, or bonded to the platform structure subsequent to molding, to create an integrated microfluidic system. In this manner, the new microfluidic platform is versatile and capable of quickly generating prototype systems, and could easily be adapted to a manufacturing setting.

    摘要: A flexible cable comprises a cable body of a silicone material and circuits in the flexible cable body. In one embodiment the flexible cable body comprises a multiple number of individual layers of poly(dimethylsiloxane). In one embodiment silicone material encapsulates the individual layers. The flexible cable is made by providing a multiplicity of substrates of a flexible silicone material, producing circuits in the substrates, and stacking the multiplicity of substrates to produce the high density flexible cable.
