Hello, We are developing an implantable device for dispensing boluses of medicine (in liquid form) that will be used for experimental research. We currently use a solenoid valve (L = 2.2 cm, dia = 0.5 cm, 12 V) to control the dispensing of the medicine (on/off) but would like to switch to a smaller system. I am looking for information about MEMS microvalves that could do the job. Thank you in advance for the response J.M. Maarek University of Southern California jmaarek@bmsrs.usc.edu
