“…Thermoelectric energy harvesting (TEH) is another promising technique that can harvest energy from ambient heat sources. The main limitations come from the threshold voltage of diodes and pass transistors and the low transistor channel conductivity due to the low output voltage (Toyama et al, 2016). Some researchers have proposed different methods to solve the issues, such as pre-charging (Carlson et al, 2010) and adding mechanically-assisted switches (Ramadass and Chandrakasan, 2011).…”

The demand for life-time power supply in Internet of Things (IoT) nodes is a challenge issue. Piezoelectric energy harvesting (PEH) is expected to meet the demand by harvesting vibration energy and converting it into electricity for the IoT nodes. This article presents a novel PEH power improvement circuit with thermoelectric energy assistance. The proposed circuit can extract energy from thermoelectric generator (TEG) to assist the PEH. Simulation and experimental platforms are built for testing the power generation performance of the proposed circuit. With the thermoelectric assistance of 0.1 V and 0.2 V, the harvested power can reach 3.4 times and 4 times that of the standard energy harvesting (SEH) circuit when the piezoelectric transducer (PZT) original open circuit voltage Voc,org = 8 V, respectively. The harvested power can be increased by 13.3% and 33.3% with the thermoelectric assistance of 0.1 V and 0.2 V, respectively.

“…Historically, the energy of nature was made use of to perform important tasks, like agriculture and transportation. Nowadays many techniques have been developed to make use of the green energy such as wind turbines [1,2], solar panels [3,4], thermal energy harvesters [5] and even hybrid systems [6,7]. These harvester devices are used to transform energy from the source into an electrical form; and each harvester produces a different electrical signal with characteristics depending on its nature.…”

“…Different algorithms are often used and many researchers suggest various ways to implement such algorithms, as well as their variations, using customized circuits [1][2][3][4][5][6][7][8][9][10], or by programming a microcontroller [11]. However, the freedom of choice among such algorithms is not allowed in low-power systems, due to the inherent trade-off between computational complexity and power consumption.…”

Sensor nodes have been assigned a lot of tasks in a connected environment that is growing rapidly. The power supply remains a challenge that is not answered convincingly. Energy harvesting is an emerging solution that is being studied to integrate in low power applications such as internet of things (IoT) and wireless sensor networks (WSN). In this work an interface circuit for a novel fluttering wind energy harvester is presented. The system consists of a switching converter controlled by a low power microcontroller. Optimization techniques on the hardware and software level have been implemented, and a prototype is developed for testing. Experiments have been done with generated input signals resulting in up to 67% efficiency for a constant voltage input. Other experiments were conducted in a wind tunnel that showed a transient output that is compatible with the target applications.
