  • Microprobe array structure and method for manufacturing the same
    Patent number: 7941201
    Abstract: A microprobe array structure with self-stabilization capability and a method for manufacturing the same are proposed. The microprobe array structure is used to sense various biopotential signals, and is characterized in that the etching parameters are controlled during etching to manufacture a microprobe structure with a reduced bottom cross section so that the microprobe can be firmly stabilized in the skin tissue. Moreover, a conducting layer is formed on the microprobe to sense signals. A design of electric isolation between microprobes is also proposed. The microprobe array can therefore be used for the measurement of various biopotential signals, and can also be used as a stimulus.

  • Method for fabricating microneedle array and method for fabricating embossing mold of microneedle array
    Patent number: 7429333
    Abstract: The present invention discloses a method for fast fabricating microneedle arrays with an embossing process and a method for fabricating an embossing mold of a microneedle array, wherein a master pattern of a high aspect ratio silicon microneedle array is fabricated with a microelectromechanical technology, and the master pattern is used to fabricate an embossing mold; a thermosetting material is filled into the embossing mold; then, baking, pressing and mold-stripping are undertaken; thereby, disposable solid polymer microneedle arrays can be batch-fabricated.
