WIRELESS CONTROL OF MICROPUMP SYSTEM USING FLEXIBLE CIRCUIT BOARD FOR IMPLANTABLE DRUG DELIVERY APPLICATIONS

Wireless communication is an important and critical issue for the micropump system for implantable drug delivery applications. For satisfying different installation requirements, the flexible circuit board is much suitable for different outer shape. As such, this paper provides a wireless implantable micropump system by flexible printed circuit board (FPCB). For normal electronic circuit design, the FR4 glass epoxy is famous in printed circuit board (PCB). Nevertheless, these PCBs are not suitable for portable device and biological applications due to the irregular surface. Therefore, a FPCB is performed for flexible application and helps to shrink the system into portable device. The micropump mainly consists of a wireless communication circuit, an antenna and a piezoelectric peristaltic micropump driving circuit. The experimental results demonstrate that the FPCB based wireless control of micropump system can deliver fluid in rates of 20ml/hr to 120ml/hr. The experimental results show that this system has minimum deviation in 0.00083. FPCB has the advantage of light, thin, flexible and suitable for portable device and animal experiments applications.
