ABSTRACT
This chapter covers the journey of different kinds of MEMS-based devices which have been covered in previous chapters, to be integrated into a single drug delivery device. This integration is addressed while addressing a pressing drug delivery device challenge which is insulin delivery. Diabetes has become a dominant disease, causing deaths the world over and such devices are quite in demand. The fabrication steps, and subsequently feasibility studies, have been performed on the proposed insulin delivery device after taking into account the development of a customized test bench for such devices. The examples discussed in this work have been taken from the earlier works done in this field and elaborated for readers’ convenience. The first example shall examine the fabrication of the IPMC membrane and its characterization as a valveless nozzle diffuser structure-based micropump. Then an insulin delivery device with microneedles and micropump is considered and its fabrication and characterization discussed for tuneable flowrate insulin delivery. Finally, as a third example an approach in IPMC membrane geometry modification is presented to achieve high flowrate.
