“…As the only temperature is considered, this approach is useful only for highly temperature-sensitive products such as fresh food, dairies, etc. Another RFID-based temperature monitoring system is presented in [21]. The presented system is designed in form of the biocompatible plaster using 130 nm CMOS technology, powered by a rechargeable lithium-ion battery.…”

In the modern world different products and goods are available throughout the world thanks to the complex supply chain system. Often products are transported on long journeys with different transportation systems where products can be damaged or spoiled. Smart Sticker is a concept for product environmental condition monitoring that can resolve some problems in the supply chain. Smart Sticker will record product environmental data in the supply chain and enable producer/consumer product monitoring. Because of ultra-low power design, Smart Sticker component selection must satisfy ultra-low power specifications, besides standard accuracy, and real-time implementation. In this paper we give an overview of the necessary measured environmental parameters and the selection of sensors with emphasis on low power design. We provided a model for the calculation of the maximum operating time, which is applied for the two Smart Sticker instances with significantly different energy consumptions. In the worst-case scenario operation time is 198 days which can be increased with a higher capacity battery

“…This is referred to as tag diversity. In [11], a plaster operating over a few centimetres at the near field communication (NFC) frequency of 13.56 MHz was presented and in [12] the most efficient tag placement for two worn ultra high frequency (UHF) tags communicating with an external reader was studied using 3 mm thick textile slotted patch antennas. The study indicated that more than two tags of the slotted patch design were required to provide coverage all around the body.…”

1. Introduction: Radio Frequency Identification (RFID) has found use in areas such as access control systems, point of sale, automatic toll collection, animal tracking, vehicle tracking and immobilization and also in the retail supply chain [1]. For medical applications, RFID technology can be used for patient tracking and safeguarding [2] as well as for equipment inventory management. RFID tags have also been used for physiological monitoring [3].The use of wireless monitoring in a hospital environment aims to improve the efficiency of patient care. Advances have seen the use of RFID technology as a standalone system or in combination with other wireless technologies [4]. Proposed battery-less wireless health sensors [5] will transmit patient vital data and therefore the risks associated with signal outage are high making it important to keep skin mounted RFID tag read failure to a minimum.Human tracking and monitoring can be achieved with RFID chips embedded in the skin [6] however this is very short read range and is inappropriate for non-permanent applications. Alternatively RFID wristbands [7] are widely used but must go on the wrist or ankle and offer only a loose contact to the skin which compromises their use for monitoring. For instance, it may not be optimal for physiological measurements such as heartbeat and pulse which require close skin contact [8]. The use of RFID for medical sensing has also been reported in works such as [9] where an adhesive sensor badge is reported for sensing biomarkers in sweat and in [10] for monitoring surface temperature.Diversity is a technique used in communication systems where alternative transmission mechanisms are introduced to reduce the chance of losing communication (signal outage). In RFID, the chances of successfully reading a tagged object or person are increased if more than one tag is used. This is referred to as tag diversity. In [11] a plaster operating over a few centimetres at the NFC frequency of 13.56 MHz was presented and in [12] the most efficient tag placement for two worn UHF tags communicating with an external reader was studied using 3 mm thick textile slotted patch antennas. The study indicated more than 2 tags of the slotted patch design were required to provide coverage all around the body. Other works such as [13] have sought to improve the performance of on-body RFID tags by using dual tag antenna diversity to reduce the probability of phase cancellation between the RFID reader continuous carrier wave and the backscattered signal from the tag. Diversity is already often implemented at the reader end and in [14] a non-RFID body mounted wireless system utilizes multiple antennas at the off-body base station. While this results in an improvement in outage, it will also lead to an increase in infrastructure
