Development of a Parallel-Computing Embedded Telemetry System for Voltammetric Microsensor and Biosensor Applications

Part of the NATO Science for Peace and Security Series C: Environmental Security book series (NAPSC)


A new parallel-computing embedded telemetry system for voltammetric microsensor and biosensor application is presented. The device, capable of driving two independent sensors, consists of a single-supply bipotentiostat-I/V converter, a parallel microcontroller unit (pMCU), a signal transmitter, and a stabilized power supply. The system is built around a new pMCU (Parallax® Propeller™) consisting of eight 32-bit independent processors called COGs. The design, construction and operation of the hardware and software are described. The system performance was evaluated in vitro on a wide range of voltammetric microsensors (dopamine, ascorbic acid, nitric oxide) and platinum-based amperometric biosensors (glucose, lactate and glutamate). This device serves as a basic model to realize an in vivo, low-power, miniaturized telemetry system built with standard hardware components readily available. The introduction of parallel computing programming techniques could permit the development of low-cost devices, reduce complex multitasking firmware development, and offer the possibility of expanding the system simply and quickly.
