“…Several fl exible rectennas have been developed [166][167][168][169] and used to power temperature, humidity, oxygen concentration, and chemical sensors. [170][171][172] To improve power density, rectennas have been integrated with other energy harvesting devices, including photovoltaics [ 142,173,174 ] and piezoelectrics, [ 175 ] and there is also the potential to transmit additional power to the antennas beyond what is available in the environment, for example using transmitters developed for RFID. Finally, a single antenna can perform multiple functions that are important for medical devices: receiving energy, transmitting excess energy to another device that is energy-starved, and sending and receiving data.…”

Advances in wireless technologies, low-power electronics, the internet of things, and in the domain of connected health are driving innovations in wearable medical devices at a tremendous pace. Wearable sensor systems composed of flexible and stretchable materials have the potential to better interface to the human skin, whereas silicon-based electronics are extremely efficient in sensor data processing and transmission. Therefore, flexible and stretchable sensors combined with low-power silicon-based electronics are a viable and efficient approach for medical monitoring. Flexible medical devices designed for monitoring human vital signs, such as body temperature, heart rate, respiration rate, blood pressure, pulse oxygenation, and blood glucose have applications in both fitness monitoring and medical diagnostics. As a review of the latest development in flexible and wearable human vitals sensors, the essential components required for vitals sensors are outlined and discussed here, including the reported sensor systems, sensing mechanisms, sensor fabrication, power, and data processing requirements.

“…In order to improve the transparency of the antenna element and reduce shadowing of solar battery surface there known investigations not only "mesh" radiators [4,12], but also radiators made of optically transparent conductive films based on Indium Tin Oxide, Antimony Tim Oxide, Titanium Indium Oxide, Gallium Zine Oxide or AgHT-4 [11,14]. There are variations of a lower degree of integration, in which the solar battery do not replace ground plane, but joined with it as an additional elements [13,16].…”

Designing problems of microstrip antennas placed on the solar battery surface and using it as a substrate are considered. Computational models taking into account the elements of its costruction and parameters of solar battery were performed by means of ANSYS HFSS. A number of numerical experiments for several antenna models were fulfilled. The aim of them is to design microstrip antenna integrated with solar battery without decreasing of solar elements effectiveness. The results of numerical experiments for several projects of microwave radiators with solid or mesh surface of the patch are presented

“…Toward this objective, solar antennas and solar-EM harvesters provide an attractive option for compact tags as both the antenna and solar cell can be carefully designed to share the same substrate area. Solar antennas have been initially proposed for satellite applications [70]; however, the recent interest in compact sensors with energy harvesting capability has led to the design of compact solar antennas [70]- [72] for autonomous battery-less sensor operation. In addition conformal solar antennas, solar rectennas, and solarpowered sensors implemented in low cost textile [73], polyethylene terephthalate (PET) [74], [75], and paper [76] substrates using thin film amorphous silicon (a-Si) solar cells have appeared in the literature.…”

No Battery RequiredO ver the last decade, radio frequency identification (RFID) systems have been increasingly used for identification and object tracking due to their low-power, low-cost wireless features. In addition, the explosive demand for ubiquitous rugged low-power, compact wireless sensors for Internet-of-Things, ambient intelligence, and biomonitoring/quality-of-life application has sparked a plethora of research efforts to integrate sensors with an RFID-enabled platform. The rapid evolution of large-area electronics printing technologies (e.g., ink-jet printing and gravure printing) has enhanced the development of low-cost RFID-enabled sensors as well as accelerated their large-scale deployment.
