PtNBridge -- A Power-Aware and Trustworthy Near Field Communication Bridge to Embedded Systems

An Improved Energy Saving Technique for Wireless Power Transfer in Near Field Communication Systems

“…Discarding the negative value (which is just a mirror), the optimum reader coil radius can be described by Equation (10). Although the magnetic force is also a consideration towards establishing the relationship in conductor area.…”

“…The NFC Reader is the active component of the NFC system that generates the magnetic field that activates the transponder, and the clock signal with which data is transferred. In this work, a generic NFC reader [10] has been modelled with ADS as a parallel RLC block with a series resistor and a signal source, as shown in Figure 2. The relationship between the power transmitted (which can be determined with the reader current 𝑖 𝑟 ) and the source voltage 𝑈 1 as shown in Equation ( 14) is defined by Ohms law.…”

“…The design of NFC readers are structured for maximum field strength requirements [9]. There is a relationship between the quality of the magnetic field and the induced voltage in NFC systems [10].…”

“…A well-documented experiment carried out by [15] revealed that; mobile phones with NFC capabilities consume more energy than those without it. Moreover, this power drain increases significantly from about 5 mW when in standby mode to about 40 mW when active [10]. Consequently, power optimization techniques for NFC systems are an ongoing field of research.…”

Facilitating a Secured Status Data Acquisition from Industrial Equipment via NFC

“…Generally, NFC interfaces into embedded system have been technically studied in [14], [15], and [16]. The case study in [17] presents a system to use NFC for device ID authentication based on digital certificates.…”
