Active liquid aspiration and dispensing based on an expanding PDMS composite
2007 (English)In: PROCEEDINGS OF THE IEEE TWENTIETH ANNUAL INTERNATIONAL CONFERENCE ON MICRO ELECTRO MECHANICAL SYSTEMS, 2007, 802-805 p.Conference paper (Refereed)
In this work we present the development of a liquid aspiration and dispensing unit which is based on a single-use thermally expanding PDMS composite. The composite actuator consists of expandable microspheres incorporated into a PDMS matrix and allows for locally altering its topography by means of individually addressable integrated heaters. Devices were designed in order to enable the generation of a cavity by the expansion of the composite actuator and are entirely fabricated from low-cost materials using wafer-level processes only. The fabricated devices successfully demonstrated controlled liquid aspiration and release thereafter of liquid volumes ranging from 180nl to 815nl.
