In this paper, a portable potentiostat with a standalone signal generator is proposed for the signal processing of vanillylmandelic acid (VMA) biosensors. The proposed potentiostat primarily consists of two microprocessors: one is used to design the programmable waveform generator, and the other is used to measure the current of the biosensors. It can perform general electrochemical analysis functions, such as cyclic voltammetry (CV), linear sweep voltammetry (LSV), differential pulse voltammetry (DPV), amperometry (IT), and potentiometry (E). In the experiment, we adopt a VMA biosensor to verify the performance of the proposed potentiostat. The experimental results show that the proposed potentiostat has the merits of good accuracy, larger range of detected sensor current, low cost, and high portability.

“…Furthermore, there is already an extensive amount of prior art on designing integrated potentiostats that contain the analog front‐end, quantizers, and digital control on a single silicon chip. These devices can outperform their discrete counterparts with pA level sensitivities and low power consumption in the μW range . Hence, on the electronic technology side, there is a relatively low barrier of entry to be able to incorporate one of these high‐performance IC potentiostat designs into a smart device such as a smartphone, tablet, or smartwatch.…”

Point‐of‐care (PoC) biosensors offer promising solutions to today's adverse and costly healthcare issues by moving diagnostic tools closer to the patient. The ubiquity of smartphones has brought about an emergence of PoC devices, which leverage the smartphone's capabilities, enabling the creation of low‐cost and portable biosensors. Electrochemical biosensors are well suited for PoC testing since the transducers can be miniaturized and inexpensively fabricated. This review paper discusses recent developments in smartphone‐based electrochemical biosensors for PoC diagnostics. These peripherals utilize the various connectivity options (for example proprietary ports, audio headphone‐jack, or wireless radio) to offload functionality to the smartphone. The smartphone‐based implementations of various electrochemical techniques, such as amperometry, potentiometry, and impedance spectroscopy are explored. Major challenges include reducing power, area, and cost of measurement circuitry, while maintaining adequate performance for PoC diagnostic applications.

“…A potentiostatic interface performs three functions: (i) it sets the cell operating voltage V cell ; (ii) it reads out the redox current at WE, I W ; and (iii) it provides analog-to-digital (A/D) conversion. Figure 10 presents general topologies for potentiostats that perform the amperometric readout relying on current to voltage (I W -to-V A ) conversion through a resistor R prior its A/D conversion [128][129][130][131]. The most common configuration is shown in Figure 10a.…”

CMOS Interfaces for Internet-of-Wearables Electrochemical Sensors: Trends and Challenges

Smart wearables, among immediate future IoT devices, are creating a huge and fast growing market that will encompass all of the next decade by merging the user with the Cloud in a easy and natural way. Biological fluids, such as sweat, tears, saliva and urine offer the possibility to access molecular-level dynamics of the body in a non-invasive way and in real time, disclosing a wide range of applications: from sports tracking to military enhancement, from healthcare to safety at work, from body hacking to augmented social interactions. The term Internet of Wearables (IoW) is coined here to describe IoT devices composed by flexible smart transducers conformed around the human body and able to communicate wirelessly. In addition the biochemical transducer, an IoW-ready sensor must include a paired electronic interface, which should implement specific stimulation/acquisition cycles while being extremely compact and drain power in the microwatts range. Development of an effective readout interface is a key element for the success of an IoW device and application. This review focuses on the latest efforts in the field of Complementary Metal–Oxide–Semiconductor (CMOS) interfaces for electrochemical sensors, and analyses them under the light of the challenges of the IoW: cost, portability, integrability and connectivity.
