| Abstract Scope |
Flexible electronic biosensors are essential for real-time patient monitoring and the delivery of personalized healthcare. These applications often require single-use sensors that are disposed of in a landfill or incinerated. To reduce the impact of electronic waste, environmentally benign fabrication technologies and decomposable materials must be used to create functional devices. Monitoring the changes in biological fluid pH is one application where these single-use sensors play a critical role in personal health management. Fluctuations in pH can indicate the onset of infection or a chronic health condition. Recent advances in printed electronics, conductive graphene inks, and laser material processing have enabled a variety of degradable carbon-based pH sensors to be fabricated. In this paper, the design and fabrication of disposable hydrogel activated discrete interdigitated capacitive (D-IDC) sensors for detecting changes in biological fluid pH is presented. Preliminary prototypes are introduced, and performance is evaluated in terms of repeatability and reproducibility |
