ELASTOMERISCHE MIKROPUMPEN- UND MIKROVENTILSYSTEME

摘要

A method of fabricating an elastomeric structure for a micropump or valve comprising: forming a first elastomeric layer on top of a first micromachined mold (10), the first micromachined mold (10) having a first raised protrusion (11) which forms a first recess (21) extending along a bottom surface of the first elastomeric layer (20); forming a second elastomeric layer (22) on top of a second micromachined mold, the second micromachined mold having a second raised protrusion (13) which forms a second recess (23) extending along a bottom surface of the second elastomeric layer, bonding the bottom surface of the second elastomeric layer onto a top surface of the first elastomeric layer such that a control channel (30) forms in the second recess between the first and second elastomeric layers; and positioning the first elastomeric layer on top of a planar substrate such that a flow channel forms in the first recess between the first elastomeric layer and the planar substrate.
