提出了一种可植入、低功耗、电化学微型泵的无线输注速率控制和可编程性。流量控制是通过调节无线接收器中电流电位计的游标位置来实现的（0.6-3.2 mA 输出电流，每步分辨率为 0.2 mA）。使用现成的蓝牙模块和 Basic Stamp 微控制器套件来启动感应功率信号的幅移键控 (ASK) 调制。在台式上实现了两种模型方案的精确流量控制。无线传输（电力传输和控制）不受放置在发射器和接收器之间的模拟组织材料的影响。
Wireless infusion rate control and programmability for an implantable, low power, electrochemical micropump is presented. Flow rate control was achieved through adjustment of the wiper position of a current potentiometer in the wireless receiver (0.6-3.2 mA output current with a resolution of 0.2 mA per step). An off-the-shelf Bluetooth module and Basic Stamp microcontroller kit was used to initiate amplitude-shift keying (ASK) modulation of the inductive power signal. Accurate flow control of two model regimens was achieved on benchtop. Wireless transmission (power transfer and control) was not affected by simulated tissue material placed between the transmitter and receiver.
