This article reviews the recent advances in the field of batteryless near-field communication
(NFC) sensors for chemical sensing and biosensing. The commercial availability of low-cost …

Point-of-care diagnostics (POC), including urine test strips, offer several advantages over
traditional laboratory-based urine analysis. POC allows us to regulate our nutritional needs …

In this paper, we present a low-cost battery-less color sensor based on Near Field
Communication (NFC). This system consists of a color sensor connected to a low-power …

In the context of home‐based healthcare monitoring systems, it is desirable that the results
obtained from biochemical tests–tests of various body fluids such as blood and urine–are …

A robust classification algorithm that applies color science and image processing techniques
is developed to automatically identify the pH level on a test strip. This algorithm is …

The implementation of near-field communication (NFC) technology in smartphones has
grown rapidly, especially due to the use of this technology as a payment system. In addition …

In this study strong HCl acid was titrated with a strong base of NaOH. Increasing pH values
were observed during such titration. Depending on the existence of indicator in the solution …

In this paper we present innovative research for the automatic interpretation of biochemical
test strip color by a smartphone using image processing techniques. Urinalysis is the current …
