Materials showing second-order nonlinear transport under time reversal symmetry can be used for Radio Frequency (RF) rectification, but practical application demands room temperature operation and sensitivity to microwatts level RF signals in the ambient. In this study, we demonstrate that BiTeBr exhibits a giant nonlinear response which persists up to 350 K. Through scaling and symmetry analysis, we show that skew scattering is the dominant mechanism. Additionally, the sign of the nonlinear response can be electrically switched by tuning the Fermi energy. Theoretical analysis suggests that the large Rashba spin-orbit interactions (SOI), which gives rise to the chirality of the Bloch electrons, provide the microscopic origin of the observed nonlinear response. Our BiTeBr rectifier is capable of rectifying radiation within the frequency range of 0.2 to 6 gigahertz at room temperature, even at extremely low power levels of −15 dBm, and without the need for external biasing. Our work highlights that materials exhibiting large Rashba SOI have the potential to exhibit nonlinear responses at room temperature, making them promising candidates for harvesting high-frequency and low-power ambient electromagnetic energy.

“…The mechanisms may be solar-based, windbased, vibrational, electromagnetic, thermoelectric, or based on ambient RF energy [217], [224]. The challenges for RF energy harvesting may include overall RF power conversion efficiency, form factor, operational bandwidth, and compactness [219]. Reference [220] provides a summary of the RF energy harvesting in the past six years.…”

She currently serves as the Vice Rector for Alumni and Career Orientation at Politecnico di Torino. She is an IEEE Fellow. Her research interests include the design of wireless network architectures, the defi nition of protocols and algorithms for mobile networks and applications, and the creation of theoretical models for the study and the performance evaluation of wireless systems. Her research is indeed a combination of system design and network-theory, aiming to design algorithms and methods that solve real problems, starting with actual data and scenarios. As far as application domains are concerned, she has been focusing on energy efficiency of wireless systems, connected cars, mobility services, service virtualization, and smart healthcare.After studying Latin and ancient Greek in high school, she decided for a change and enrolled in the Electrical Engineering B.S. and M.Sc. Program at the University of Florence, Italy. She did her Master thesis on security in wireless networks under the supervision of Prof. Aura Ganz, at the University of Massachusetts at Amherst, MA, and received her Ph.D. from Politecnico di Torino in 2000. During her Ph.D., she was a visiting scholar at the University of California at San Diego (UCSD), CA, working with Prof. Ramesh Rao. She was then a visiting researcher at UCSD in 2000-2003. These experiences gave her the unique opportunity to explore highly innovative aspects in energy efficiency of wireless communication devices as well as in local and personal wireless networks. In particular, she developed pioneering, highly inter-disciplinary work on the modeling of battery behavior in mobile devices and the designing of algorithms and protocols aiming at establishing the optimal tradeoff between energy saving and the level of user's quality of service. At UCSD she had the opportunity to also work with Prof. John Proakis and to participate in research projects involving large companies. Afterwards, she started investigating the coexistence between diff erent wireless technologies, and cooperation in distributed wireless networks through the lens of game theory.

This paper described a four-band implantable RF rectifier with simplified circuit complexity. Each RF-rectifier cell is sequentially matched to the four operational frequencies to accomplish the proposed design. The proposed RF rectifier can harvest RF signals at 1.830, 2.100, and white space Wi-Fi bands between 2.38 to 2.68 GHz, respectively. At 2.100 GHz, the proposed RF harvester achieved a maximum (radio frequency direct current) RF-to-DC power conversion efficiency (PCE) of 73.00% and an output DC voltage $$V_{DC}$$ V DC of 1.61 V for an RF power of 2 dBm. The outdoor performance of the rectenna shows a $$V_{DC}$$ V DC of 0.440 V and drives a low-power bq25504-674 evaluation module (EVM) at 1.362 V. The dimension of the RF-rectifier on the FR-4 PCB board is 0.27$$\lambda _{g}$$ λ g $$\times$$ × 0.29$$\lambda _{g}$$ λ g . The RF-rectifier demonstrates the capacity to effectively utilize the frequency domain by employing multi-band operation and exhibiting a good impedance bandwidth through a sequential matching technique. Thus, by effectively controlling the rectenna’s ambient performance, the proposed design holds the potential for powering a range of low-power biomedical implantable devices. (BIDs).
