Portable diagnostic tools enable the next generation of in-home sensing and biosensing devices for screening of pathologies and monitoring of physiological parameters. In this context, the reduction in cost of off-the-shelf electronics components is rapidly advancing the development of affordable and easy-to-use portable platforms. In this work we describe the development of a multisensing platform capable of simultaneously or concurrently performing three electrochemical measurements that can provide information in real time about the levels of important physiological markers, namely pH, antioxidant capacity and conductivity of biofluids. The developed device can be wirelessly powered via an inductive charging module and an onboard battery and transmits data via Bluetooth to a mobile device for rapid and simple data sharing and processing. By integrating multiple types of electrochemical sensors into an inexpensive, pocket-sized diagnostic tool, we demonstrate a low-cost approach to point-of-care health monitoring using open-source hardware that can be readily deployed in resource-limited settings. These types of inexpensive sensing modalities have the potential to provide actionable health information as initial screening markers for the onset of several systemic diseases.

Abstract
Portable diagnostic tools enable the next generation of in-home sensing and biosensing devices for screening of pathologies and monitoring of physiological parameters. In this context, the reduction in cost of off-the-shelf electronics components is rapidly advancing the development of affordable and easy-to-use portable platforms. In this work we describe the development of a multisensing platform capable of simultaneously or concurrently performing three electrochemical measurements that can provide information in real time about the levels of important physiological markers, namely pH, antioxidant capacity and conductivity of biofluids. The developed device can be wirelessly powered via an inductive charging module and an onboard battery and transmits data via Bluetooth to a mobile device for rapid and simple data sharing and processing. By integrating multiple types of electrochemical sensors into an inexpensive, pocket-sized diagnostic tool, we demonstrate a low-cost approach to point-of-care health monitoring using open-source hardware that can be readily deployed in resource-limited settings. These types of inexpensive sensing modalities have the potential to provide actionable health information as initial screening markers for the onset of several systemic diseases.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
