Abstract
Near-field communication is a new kind of low-cost wireless communication technology developed in recent years, which brings great convenience to daily life activities such as medical care, food quality detection, and commerce. The integration of near-field communication devices and sensors exhibits great potential for these real-world applications by endowing sensors with new features of powerless and wireless signal transferring and conferring near field communication device with sensing function. In this review, we summarize recent progress in near field communication sensors, including the development of materials and device design and their applications in wearable personal healthcare devices. The opportunities and challenges in near-field communication sensors are discussed in the end.
Highlights
With the advent of the Internet-of-Things (IoT) in the 21st century, wearable electronics technology will play critical roles in diverse fields of healthcare, food safety, security, etc. [1]
Ultrahigh frequency (UHF) radio frequency identification (RFID) technologies have been applied into the market, and several commercial sensors have been developed in logistics, inventory, and supply-chain applications [25,26,27]
Many sensitive near-field communication (NFC) integrated circuit (IC) with the ability of energy harvesting have been available in the market, and NFC sensors based on energy harvesting have many applications, which can facilitate the development of low-cost and green energy wearable devices [44,45]
Summary
With the advent of the Internet-of-Things (IoT) in the 21st century, wearable electronics technology will play critical roles in diverse fields of healthcare, food safety, security, etc. [1]. Integrating wearable devices with wireless communication data transmission provides new functions of real-time monitoring and dynamic response. Wireless communication technologies, such as radio frequency identification (RFID) and Bluetooth, have been widely used in wearable electronics for information transmission [2]. NFC is a promising tool for physiological signal measurement with features such as battery-less in passive mode, wireless communication, fast and non-contact data transmission [3,4,5] It has achieved successful applications in commercial consumption field by providing convenient payment methods, which gradually replaced the traditional way of paying with banknotes [6]. Some excellent representative devices equipped with NFC sensors are selected to illustrate the wide range of potential applications, for example, healthcare, food safety, and plant growth. The perspective of NFC sensors is discussed in the end
