In this letter, we present a custom-designed and flexible readout circuitry for the characterization of flexible and planar electrolyte-gated carbon nanotube field-effect transistor-based biosensors for ammonium detection in sweat. We employed spray-deposi ...

Truly wearable, fully flexible, and multiparametric sweat analysis with soft and socially discrete packaging offers tremendous potential to enable the next generation of noninvasive digital biomarkers analysis. Several examples of miniaturized potentiometr ...

Traditional analog front-ends for biomedical signal acquisitions operate at very low frequencies (Hz-range) and are severely affected by flicker and environmental noise, which degrade the quality of low-frequency signals, thereby reducing the signal-to-noi ...

Malaria continues to pose a significant global health challenge, with substantial impediments arising from the need for more reliable, effective, and economically viable diagnostic tools, particularly for early detection. This research introduces a novel m ...

This paper presents an ultra-miniaturized, ultra-low-power, capacitor-less CMOS ring oscillator based on dynamic leakage suppression technique. Measurement results demonstrated an oscillation frequency of 21.89 kHz and a power consumption of 7.9 nW for a s ...

Electrochemical sensors integrated with CMOS circuits play a pivotal role in quantifying various chemicals across a huge spectrum of applications, prominently in distributed diagnostics and remote monitoring. When designing integrated devices, meticulous c ...

This paper systematically demonstrates the feasibility of wirelessly monitoring dopamine concentration in the brain with an implantable biosensor. The biosensor was realized using microwires, and then, the dopamine concentration was measured in-vitro rangi ...
