Fabrication of drug delivery MEMS devices

Abstract

There is considerable amount of interest in the immediate treatment of personnel involved in high risk situations on the battlefield. A novel approach to drug delivery on the battlefield based on MEMS technology is discussed. By combining three separately fabricated layers, a single implantable drug delivery device capable of delivering up to 100 mm3 of a vasopressin solution was developed. In vitro release of vasopressin was observed and the I-V response of the bubble generator was characterized. Results show that the voltage at the time of release is ~11V while the current is ~0.35A, giving a power output of 3.79W. The time to total release of the drug was less than 2 minutes.
