“…Powerfilm's ultrathin (200 μm) and ultraflexible SP3-37 hydrogenated amorphous silicon (a-Si:H) PV ambient light-energy-harvesting transducer [23], positioned on top of the antenna, is connected to the power management subsystem, located on the node's feed plane. This particular PV module is selected because of four multidisciplinary reasons.…”

“…First, the SP3-37 harvester exhibits a broad spectral response, not only enabling energy harvesting from solar light but also from the most frequently available light sources in an indoor environment [9], [23]. More specifically, the SP3-37 PV module is characterized by a maximum output voltage of 3 V at 22 mA under full sunlight (107 527 lx) and a maximum output voltage of 2.5 V at 100 μA under typical office lighting (330 lx) [23]. Second, its flexible and ultrathin structure permits a conformal and low-profile integration [44].…”

“…This, however, introduces novel, stringent design requirements. First, the enhanced RFID tag functionality and larger operating range make system autonomy one of the major critical design constraints [21], [23]. Powering enhanced RFID tags exclusively by RF energy transmitted by RFID readers restricts data logging, sensing, and computational operations to the coverage range of the RFID reader [23], [27].…”

Reliability, functionality, and operation range may be increased [9], [23] by combining an antenna with high radiation efficiency and tailored radiation pattern [9], [28] with energy harvesters relying on ambient sources, such as vibration [29], kinetic [17], solar [23], [30], or RF energy [26].…”

Abstract-A novel wearable radio frequency identification (RFID) tag with sensing, processing, and decision-taking capability is presented for operation in the 2.45-GHz RFID superhigh frequency (SHF) band. The tag is powered by an integrated light harvester, with a flexible battery serving as an energy buffer. The proposed active tag features excellent wearability, very high read range, enhanced functionality, flexible interfacing with diverse low-power sensors, and extended system autonomy through an innovative holistic microwave system design paradigm that takes antenna design into consideration from the very early stages. Specifically, a dedicated textile shorted circular patch antenna with monopolar radiation pattern is designed and optimized for highly efficient and stable operation within the frequency band of operation. In this process, the textile antenna's functionality is augmented by reusing its surface as an integration platform for light-energy-harvesting, sensing, processing, and transceiver hardware, without sacrificing antenna performance or the wearer's comfort. The RFID tag is validated by measuring its stand-alone and on-body characteristics in free-space conditions. Moreover, measurements in a real-world scenario demonstrate an indoor read range up to 23 m in nonlineof-sight indoor propagation conditions, enabling interrogation by a reader situated in another room. In addition, the RFID platform only consumes 168.3 µW, when sensing and processing are performed every 60 s.Index Terms-Battery-assisted, energy harvesting, Internet of Things (IoT), radio frequency identification (RFID), textile antenna, wearable.

Professor Stavros GeorgakopoulosThis research investigates the implementation of battery-less RFID sensing platforms inside lossy media, such as, concrete and grout. Both concrete and novel grouts can be used for nuclear plant decommissioning as part of the U.S. Department of Subsequently, the measured complex permittivity is used to formulate analytical Debye models. Also, the transmission and propagation losses of a uniform plane wave inside grout are calculated. Our results show that wireless sensors will perform better in vi concrete than grout. In addition, the maximum axial and radial ranges for WISP are experimentally determined. Our work illustrates the feasibility of battery-less wireless sensors that are embedded inside concrete and grout. Also, our work provides information that can be used to optimize the power management, sampling rate, and antenna design of such sensors.

In this article the theory and practice of radiative wireless power transfer (RWPT) is discussed. The position of RWPT in the spectrum of power harvesting techniques is outlined and the history of RWPT, finding its origin in the electromagnetic radiation experiments of Heinrich Hertz, is briefly provided. Next, RWPT basics are explained, in particular antenna theory, the Friis transmission equation, and the impedance matching of an antenna to a rectifying circuit. The rectifying antenna (or rectenna) is discussed next and several prototypes are also presented in detail.
