We present a small, compact and low-power electronic instrumentation for a point-of-care (PoC) device for the early diagnosis of diabetes mellitus and associated risk factors. The presented system consists of a low-power 4-channel potentiostat, a transducer with 4 separate electrochemical cells featuring different biosensors, and a low-cost printed battery. The system is designed to measure key parameters on diabetes mellitus analysis, such as: glucose, cholesterol and triglycerides. It has been designed as a disposable device using a single blood drop to quantify these parameters, enhancing disposition decision time and improving patient satisfaction when compared with current analytical methodology. The electronic instrumentation has been designed to simultaneously control and read the measurement of the 4 different sensors on the transducer block/chip. In this paper, we present the previous evaluation of the system through different cyclic voltammetry and chronoamperometry analysis compared with a commercial multichannel potentiostat 1030B from CH Instruments. The system presents accurate and reliable performance powered by a printed electrochemical battery.

We present a small, compact and portable envisaged lab-on-a-chip (LoC) device for point-of-care (PoC) detection of different key parameters on diabetes mellitus analysis; glucose, cholesterol, triglycerides and hematocrit. These four parameters, present in blood samples, are important in the standardized analysis affecting different patients with different medical conditions. The quantification of glucose, cholesterol, triglycerides and hematocrit it is performed with a single disposable device using a single blood drop, enhancing disposition decision time and improving patient satisfaction when compared with actual analytical methodology, and it is an easy to use device and no skilled personnel is needed to use it, avoiding the use of more complicated processes like phlebotomy. The presented device consists of a custom sensing system, low power electronic instrumentation and an easy user interpretation readout display, powered by a single battery.
