    Filed: August 7, 2009
    Date of Patent: April 1, 2014
    Assignee: Robert Bosch GmbH
    Inventors: Julia Cassemeyer, Ralph Reichenbach
  • Method for manufacturing a micropump and micropump
    Patent number: 8607450
    Abstract: A method for manufacturing a micropump, which may be for the metered delivery of insulin, multiple layers being situated on the front side of a first carrier layer, which has a front side and a rear side, and microfluidic functional elements being formed by structuring at least one of the layers. It is provided that the structuring of the at least one layer for manufacturing all microfluidic functional elements is exclusively performed by front side structuring. Furthermore, a micropump is disclosed.

  • Method for producing porous microneedles and their use
    Patent number: 8354033
    Abstract: A method for producing porous microneedles (10) situated in an array on a silicon substrate includes: providing a silicon substrate, applying a first etching mask, patterning microneedles using a DRIE process (“deep reactive ion etching”), removing the first etching mask, at least partially porosifying the Si substrate, the porosification beginning on the front side of the Si substrate and a porous reservoir being formed.
