Controlling a Drug Delivery Micropump Using Surface Acoustic Wave Correlator

A secure self-biased remote controller for precisely adjusting the micropump of a drug delivery system, working at 956 MHz, is proposed. The controller transceiver is secured byusing a Barker code sequence. Surface acoustic wave device, as a bandpass filter, is designed with minimum insertion loss and asharp bandwidth matching the single frequency of operation. In the receiver, a correlation is introduced between input coddedelectromagnetic wave and output Inter Digital Transducers(IDTs), creating an output voltage that electrostatically actuates the micropump diaphragm. The finite element simulation resultsshow that the actuation voltage is a function of the coded input signal. Besides, a maximum voltage with amplitude of 5.8 V iscreated only at coded frequency. The generated voltage creates 9.3353 nm displacement in the conductive microdiaphragm of the micropump.
