Techniques for wireless energy harvesting (WEH) are emerging as a fascinating set of solutions to extend the lifetime of energy-constrained wireless networks, and are commonly regarded as a key functional technique for almost perpetual communications. For example, with WEH technology, wireless devices are able to harvest energy from different light sources or Radio Frequency (RF) signals broadcast by ambient or dedicated wireless transmitters to support their operation and communications capabilities. WEH technology will have increasingly wider range of use in upcoming applications such as wireless sensor networks, Machine-to-Machine (M2M) communications, and the Internet of Things. In this paper, the usability and fundamental limits of joint RF and solar cell or photovoltaic harvesting based M2M communication systems are studied and presented. The derived theoretical bounds are in essence based on the Shannon capacity theorem, combined with selected propagation loss models, assumed additional link nonidealities, diversity processing, as well as the given energy harvesting and storage capabilities. Fundamental performance limits and available capacity of the communicating link are derived and analyzed, together with extensive numerical results evaluated in different practical scenarios, including realistic implementation losses and state-of-the-art printed supercapacitor performance figures with voltage doubler-based voltage regulator. In particular, low power sensor type communication applications using passive and semi-passive wake-up radio (WuR) are addressed in the study. The presented analysis principles and results establish clear feasibility regions and performance bounds for wireless energy harvesting based low rate M2M communications in the future IoT networks.

“…[43][44][45] Thanks to the progressive improvement of integrated circuit design, some signal processing circuits and ultra-low-power microcontrollers consume only a microwatt of power nowadays. [46][47][48] Thus, the generated power from the HBBTs could suffice to power up complex circuits and self-powered autonomous alert systems. Furthermore, being as fibers/yarns or fabrics, HBBTs could also be implemented in large dimensions enabling a large area sensing and mapping our body's health.…”

The rise of wearable technology has gradually shifted modern health monitoring from clinical to personal use. Smart wearables can collect physiological signals and show them directly on a smartphone. In contemporary healthcare scenarios, this big data could aid medical doctors in online health analysis. Most currently available wearables are designed to monitor specific health parameters, while the combination of many devices is practically not convenient and not cost-effective. Therefore, a strong trend is towards the development of multifunctional devices. This demands, however, alternative sources of power other than conventional batteries. The concept of human-body-powered biosensing textiles (HBBTs) addresses this challenge. By harvesting energy produced from the human body such as motion, pressure, vibration, heat, and metabolites and converting them into electricity, HBBTs could potentially work without a battery. Additionally, the textiles themselves provide a suitable substrate for interconnects and biosensors, such that a system based on HBBTs could provide multifunctional health monitoring. This review explains the fundamental theories, the classification, the energy-conversion efficiency assessment, and the possible biomonitoring applications of HBBTs. Furthermore, we discuss the challenges for technology maturity and the perspectives of HBBTs in shaping the future of health monitoring.
