“…Therefore, it is preferred to make the sensors self-contained with their own renewable power supply. Recent advances in lowpower sensor technology have reduced power requirements to the level of only several milliwatts [1,2], which makes the concept of a self-powered WSN feasible. Some possible energy sources for WSN include photonic energy [3], thermal energy [4] and mechanical energy [5].…”

a b s t r a c tVibration-based micro-generators, as an alternative source of energy, have become increasingly significant in the last decade. This paper presents a new tunable electromagnetic vibration-based micro-generator. Frequency tuning is realized by applying an axial tensile force to the micro-generator. The dimensions of the generator, especially the dimensions of the coil and the air gap between magnets, have been optimized to maximize the output voltage and power of the micro-generator. The resonant frequency has been successfully tuned from 67.6 to 98 Hz when various axial tensile forces were applied to the structure. The generator produced a power of 61.6-156.6 W over the tuning range when excited at vibrations of 0.59 m s −2 . The tuning mechanism has little effect on the total damping. When the tuning force applied on the generator becomes larger than the generator's inertial force, the total damping increases resulting in reduced output power. The resonant frequency increases less than indicated from simulation and approaches that of a straight tensioned cable when the force associated with the tension in the beam becomes much greater than the beam stiffness. The test results agree with the theoretical analysis presented.

“…Another network protocol called Wearable Based Sensor Networks (WBSNs), based on IEEE 802.15.4 was introduced that had different probable applications like the ECG-based system, a wearable platform for light, audio, motion and temperature sensing [95]. Toumaz Technologies, UK devised a wireless system-on-chip integrated system where the transceiver operates between 862-870 MHz and 902-928 MHz ISM bands in European and North American countries respectively [96]. Research projects with antennas and RF systems integrated into clothes have also been progressed working on Body Area Network (BAN) where the low powered devices would be surface mounted on the clothing in a fixed position [97].…”

Abstract-The paper provides a review on some of the significant research work done on wearable flexible sensors (WFS). Sensors fabricated with flexible materials have been attached to a person along with the embedded system to monitor a parameter and transfer the significant data to the monitoring unit for further analyses. The use of wearable sensors has played a quite important role to monitor physiological parameters of a person to minimize any malfunctioning happening in the body. The paper categorizes the work according to the materials used for designing the system, the network protocols and different types of activities that were being monitored. The challenges faced by the current sensing systems and future opportunities for the wearable flexible sensors regarding its market values are also briefly explained in the paper.

On the brink of introducing the fifth generation (5G) of cellular networks, the art of radio-frequency (RF) integrated circuit design has never seen such a wide spread of diverging requirements:On the one hand, ubiquitous sensor networks are mandating power budgets in the order of micro-watt. They should be constructed as energy-autonomous, wireless, low-cost sensor nodes. This demand is caused by massive deployment scenarios of billions of devices, which makes wires and batteries unpractical. As a result, the desire for the radio nodes to harvest their operational energy from the environment emerges.On the other hand, the recent and ongoing realization of gigabit-per-second capable cellular modems is driving hardware and power requirements to extremes. To overcome hardware limitations, introduced by analog impairments, digital correction and alignment algorithms are employed for compensation. These factors call for usage of expensive advanced CMOS technology nodes and increased utilization of digital signal processing techniques.In this paper, we recap ongoing trends and developments for ultra-low power and high-end transceiver (TRX) designs using CMOS technology nodes ranging from low-cost to highest performance.Keywords: RF; ultra-low-power; wireless architectures; transceiver; mixed-signal circuits; 5G Von Mikrowatt zu Gigabit: Herausforderungen beim Design moderner Funkübertragungssysteme. Neben der Einführung der zellularen Mobilfunknetze der fünften Generation (5G) muss sich auch die integrierte HochfrequenzSchaltungstechnik einer noch nie dagewesenen Breite an unterschiedlichen Anforderungen stellen: Auf der einen Seite gibt es überall kabellose Sensornetzwerke, denen nur eine geringe Menge an Versorgungsleistung im MikrowattBereich zur Verfügung steht. Daher müssen die Chips in diesem Bereich energieautark und möglichst kostengünstig entwickelt werden. Aufgrund der zu erwartenden hohen Stückzahlen (Milliarden von unterschiedlichsten Sensoren für verschiedene Anwendungen) sind eine drahtgebundene Energieversorgung oder der Einsatz von Batterien in vielen Fällen praktisch unmöglich. Somit wird es für die Sensoren immer wichtiger, ihre Energieversorgung aus der Umgebung zu gewinnen (Stichwort Energy Harvesting).
