“…Although linear regulators are less efficient than switching ones, the former are simpler to use, low cost, have low noise, and have no AC switching losses. [22] In the system proposed here, when VR is off, C is isolated from the load; when VR is on, the stored voltage in C is transferred to the load. The ON/OFF control is achieved by two voltage dividers (R 1 ÀR 2 and R 3 ÀR 4 ), an operational amplifier (OA1) configured as a voltage comparator, and a normally closed push button (PB), which opens when pressed and closes when released.…”

A system that aims to manage the energy harvested from the finger movement using a glove‐type garment is proposed. For this, five polyvinylidene difluoride (PVDF) film‐type sensors are mounted on different interphalangeal joints of the fingers. A 68 μF/25 V ceramic capacitor is used as a storage device. A battery‐less power management circuit (PMC) is proposed to isolate the capacitor from the load to reduce the current consumption while charging. When the voltage across the capacitor reaches a threshold voltage, the user decides when to transfer the energy to the electronic load. To test the proposed system, the harvested and conditioned energy is used to power both the PMC and a battery‐less cardiac pulse detection circuit, achieving an autonomy of 20 s. This time depends on the voltage stored in the capacitor and the current consumption of the load. Using the proposed wearable system, it is possible to store up to 700 μJ in the capacitor when a subject manipulates a computer or a cellular phone for 10 min. The proposed system is not limited to the activities presented herein because it can harvest the biomechanical energy from any activity that involves finger movements.

“…In EH systems, PMCs work by switching or triggering between energy-storage and energy-delivery phases [22,23] but under certain conditions, usually threshold voltages and/or load requirements, [18] so the load is powered intermittently. In this proposal, a different approach is used.…”

Internet of Things (IoT)is the third wave of economy after the first and second being agriculture and industry, respectively, paving the way for the fourth industrial revolution (4IR). IoT is a combination of all the revolutionary technologies in the last two centuries. More than a billion of smart devices have been developed across the world by more than 10 vendors to satisfy billions of needs that are trusted by 98% of economic actors. This study describes design and implementation of IoT architectures stressing on scalability, integration, and interoperability of heterogeneous IoT systems. It gives answers toi) how systems can be designed to become easily configurable and customizable for a specific IoT infrastructure? And ii) how Investors, producers and consumers can be integrated on the same page of an IoT platform? We have developed a master database and directories from top chart IoT nomenclature, frameworks, vendors, devices, platforms and architectures and gathered data from 27 big online resources commonly used by Forbes, Business week and CNBC. Also, datasheets of IoT equipment by vendors (e.g. Intel, IBM, ARM, Microchip, Schneider, and CISCO), used tools (e.g. Lab center Proteus, AutoCAD and Excel), and platforms (e.g. Visual Studio, Eclipse) are combined to build directories of plethora of data. The main outcome of this work culminates in providing a seamless solution and recommendations for various infrastructures (hardware and software), for effective and integrated resource utilization and management in an IoT perspective.

“…They are also heavy, especially when compared with microelectronic devices to which they supply power. A typical battery has a short life span and is thus not practical for devices, which are expected to last more than 10 years [24,25]. In addition, some electronic devices are located in hard-to-reach areas: embedded in people or animals, installed inside structures (bridges, roads, and buildings), placed in satellite systems, etc.…”

The demand for power is increasing due to the rapid growth of the population. Therefore, energy harvesting (EH) from ambient sources has become popular. The reduction of power consumption in modern wireless systems provides a basis for the replacement of batteries with the electromagnetic energy harvesting (EMEH) approach. This study presents a general review of the EMEH techniques for autonomous sensor (ATS) applications. Electromagnetic devices show great potential when used to power such ATS technologies or convert mechanical energy to electrical energy. As its power source, this stage harvests ambient energy and features a self-starting and self-powered process without the use of batteries. Therefore, it consumes low power and is highly stable for harvesting energy from the environment with low ambient energy sources. The review highlights EMEH circuits, low power EMEH devices, power electronic converters, and controllers utilized in numerous applications, and described their impacts on energy conservation, benefits, and limitation. This study ultimately aims to suggest a smart, low-voltage electronic circuit for a low-power sensor that harvests electromagnetic energy. This review also focuses on various issues and suggestions of future EMEH for low power autonomous sensors.
