This paper presents a holistic and authoritative review of the role of microwave technologies in enabling a new generation of wearable devices. A human-centric Internet of Things (IoT) covering remote healthcare, distributed sensing, and consumer electronics, calls for high-performance wearable devices integrated into clothing, which require interdisciplinary research efforts to emerge. Microwaves, the "interconnect" of wireless networks, can enable, rather than solely connect, the next generation of autonomous, sustainable, and wearable-friendly electronics. First, enabling technologies including wireless power transmission and RF energy harvesting, backscattering and passive communication, RFID, and electromagnetic sensing are reviewed. We then discuss the key integration platforms, covering smart fabrics and electronic textiles, additive manufacturing, printed electronics, natively-flexible and organic RF semiconductors, and fully-integrated CMOS systems, where opportunities for hybrid integration are highlighted.

“…Note that simple narrow band antennas can be used since all involved signals are located around f 0 . Finally and unless otherwise specified, the generator transmits a double-sideband suppressed carrier modulation [i.e., with a = 0 and b = 1 in (10)] with f m = 1 kHz.…”

“…For the read range, a query command is generated using the vector generator, read range is extracted from the minimum power at which the RN16 can be detected by the spectrum analyzer. For the detection range, a double-sideband suppressed carrier modulation [i.e., with a = 0 and b = 1 in (10)] is generated and the tag is detected based on the presence of the harmonics at f 0 ± 3f m . Note that the exact same instruments and configuration are used for both ranges.…”

“…Other techniques, based on intermodulation, have also been proposed to generate new frequency components around the carrier frequency [6], [7]. Intermodulation is also able to carry data like in [8]- [10] where a replica of the input signal at a slightly different frequency is backscattered by the transponder. Compared to [3]- [5], in the proposed method, all involved signals remain around the fundamental frequency which significantly reduces the complexity of the reading system.…”

This paper presents a new modulation and detection scheme for UHF RFID tags. This detection method is not based on the load switching modulation classically used by the tag to communicate with the reader. The principle relies on the generation of a modulated signal by the reader combined with the non-linearity present in any RFID chip (or other nonlinear devices). Under specific conditions, we show that the backscattered signal by the tag due to the non-linearity can produce new frequency components located around the carrier frequency used by the reader. These new components can be easily separated from the leakage and the response of the environment in the frequency domain. Moreover this detection can be done at a power which is significantly lower than the sensitivity of the chip. Thus, the associated detection range can be higher than the classical read range of the tag. In measurements, this detection range can be higher than 20 m for a fully passive tag and represents an enhancement of 30% compared to the classical read range.
