In this work, a low power and robust electroactive microwell-based implantable drug delivery system, intended for use with autonomous microsystems, is presented. The device comprises of an upper silicon based structure in which the drug storage sites are defined and a lower electrically functionalized PDMS (polydimethylsiloxane) backing. The drug ejection mechanism developed here exploits localized electrokinetic effects to control both the release time and release rate of chemicals stored in… CONTINUE READING
