“…NFC-based battery-free electrochemical sensors can harvest radio frequency energy to acquire and transmit data to a smartphone over a short distance, making them suitable as an enabling technology for PoCT. As a result, various battery-less NFC-based sensors have been proposed in the literature for several applications [ 16 , 17 ] including biomedical ones [ 14 , 18 , 19 ].…”

This work studies the feasibility of using a battery-less Near-Field Communication (NFC) potentiostat for the next generation of electrochemical point-of-care sensors. A design based on an NFC microchip, a microcontroller, and a custom potentiostat based on an operational amplifier is presented. A proof-of-concept prototype has been designed and used to quantify glucose concentration using commercial glucose test strips from chronoamperometry measurements. The device is harvested and the sensor is read using a mobile phone. The prototype uses an antenna loop covered with ferrite sheets to ensure stable operation of the electronics when the mobile phone is used as reader. The use of ferrite reduces the detuning caused by the proximity of the metal parts of the mobile phone. A comparison with a commercial glucometer device is provided. Results obtained using a commercial glucometer and those provided by the proposed potentiostat show an excellent agreement.

“…It is widely explored as a tool for the efficient delivery of services, including in healthcare. Smartphones have been explored as a readout method for both optical and electrical signals [ 123 , 124 , 125 ]. For optical signals, a smartphone camera is used for data acquisition [ 126 , 127 , 128 ].…”

Role of Paper-Based Sensors in Fight against Cancer for the Developing World

et al. 2022

Cancer is one of the major killers across the globe. According to the WHO, more than 10 million people succumbed to cancer in the year 2020 alone. The early detection of cancer is key to reducing the mortality rate. In low- and medium-income countries, the screening facilities are limited due to a scarcity of resources and equipment. Paper-based microfluidics provide a platform for a low-cost, biodegradable micro-total analysis system (µTAS) that can be used for the detection of critical biomarkers for cancer screening. This work aims to review and provide a perspective on various available paper-based methods for cancer screening. The work includes an overview of paper-based sensors, the analytes that can be detected and the detection, and readout methods used.

“…A key advantage of SbSs is the possibility to wirelessly transmit data via cellular data, Wi-Fi, Bluetooth, or, Near Field Communication (NFC); for a detailed technical description of wireless SbSs readers should refer to Ref. [190]. However, there are risks associated with wireless data transfer; if a network is not secure, people with wireless-enabled devices within the vicinity can 'piggyback' onto the connection and possibly intercept the data [191].…”
