Hello everyone!

More and more people are joining us to follow the Energy Harvesting news! I wish you a warm welcome!

As a reminder: This monthly newsletter lists the most impactful scientific articles of the last month, the market opportunities in the current trend, a section to learn more about energy harvesting through other formats and finally the next meetings not to be missed!

This month, a scientific article caught my attention, it’s about the latest advances in Energy Harvesting in the aquatic environment, more precisely on the recent advances of Triboelectric Nanogenerators for Marine Exploitation.

In the “Learning Content” section, I have selected some content about the recent technological advances.

A battery-less wireless implant for the continuous monitoring of vascular pressure, flow rate and temperature

Devices for monitoring blood haemodynamics can guide the perioperative management of patients with cardiovascular disease. Current technologies for this purpose are constrained by wired connections to external electronics, and wireless alternatives are restricted to monitoring of either blood pressure or blood flow. Here we report the design aspects and performance parameters of an integrated wireless sensor capable of implantation in the heart or in a blood vessel for simultaneous measurements of pressure, flow rate and temperature in real time. The sensor is controlled via long-range communication through a subcutaneously implanted and wirelessly powered Bluetooth Low Energy system-on-a-chip… Read more…

Staggered circular nanoporous graphene converts electromagnetic waves into electricity

Harvesting largely ignored and wasted electromagnetic (EM) energy released by electronic devices and converting it into direct current (DC) electricity is an attractive strategy not only to reduce EM pollution but also address the ever-increasing energy crisis. Here we report the synthesis of nanoparticle-templated graphene with monodisperse and staggered circular nanopores enabling an EM–heat–DC conversion pathway. We experimentally and theoretically demonstrate that this staggered nanoporous structure alters graphene’s electronic and phononic properties by synergistically manipulating its intralayer nanostructures and interlayer interactions… Read more…

Colour-changing crystal could be used for harvesting water vapour

A decade ago, a Polish postdoctoral fellow working in South Africa noticed how a porous crystal of an unusual organic compound switches between yellow and red, depending on the humidity level. Now a paper in Nature reveals for the first time how the compound takes up and releases water vapour in conditions ranging from room temperature to as low as -70 °C, because of microscopic channels, each a hundred thousandth the diameter of a human hair.

Supramolecular chemists from Stellenbosch University (SU), in South Africa, and Adam Mickiewicz University, in Poland, hope that their work will help with the design of energy-efficient devices to harvest water from the atmosphere in arid regions. Their findings could also help find solutions for controlling indoor humidity… Read more…

On high-performance rotational energy harvesting with a novel cam-like dielectric elastomer generator

Rotational energy is a type of common energy source that can be harvested for supplying low-powered electronic devices. This paper proposes and investigates a novel cam-like dielectric elastomer generator (CDEG) for high-performance rotational energy harvesting. A mushroom-head clamp is designed to form a type of advanced conical dielectric elastomer membranes (DEMs). Moreover, a type of multi-protrusion cam mechanism is designed in the CDEG to effectively convert any external rotational excitation into a linear reciprocating motion, which can be further converted into electricity through the DEMs… Read more…

Recent Advances in Triboelectric Nanogenerators for Marine Exploitation

The ocean, as one of the most important areas for human production and living, plays a vital role in transportation, food production, and energy supply. However, it is greatly desired to develop relevant advanced technologies to achieve efficient and safe ocean exploitation and utilization. The advanced triboelectric nanogenerator (TENG), which can transform mechanical motion into electric energy to achieve the harvesting of related mechanical energy and obtain corresponding mechanical motion characteristics by the corresponding electronic signal, is a significant choice to develop the corresponding advanced technologies for marine exploitation… Read more…

The promising future of triboelectric nanogenerators in marine exploitation

(Nanowerk Spotlight) Triboelectric nanogenerators (TENGs) are rapidly emerging as a cutting-edge technology with the potential to revolutionize the marine industry. As a novel technology that has made significant progress over the past decade, TENGs have been regarded as one of the most efficient methods for harvesting low-frequency ocean energy.By converting mechanical motion into electrical energy, TENGs enable the harvesting of associated mechanical energy while simultaneously capturing the characteristics of the mechanical motion through corresponding electronic signals… Read more…

Next-Generation Wind Technology

The Wind Energy Technologies Office (WETO) works with industry partners to increase the performance and reliability of next-generation wind technologies while lowering the cost of wind energy. The office’s research efforts have helped to increase the average capacity factor (a measure of power plant productivity) from 22% for wind turbines installed before 1998 to an average of nearly 35% today, up from 30% in 2000. Wind energy costs have been reduced from over 55 cents (current dollars) per kilowatt-hour (kWh) in 1980 to an average of under 3 cents per kWh in the United States today. To ensure future industry growth, wind industry technology must continue to evolve, building on earlier successes to further improve reliability, increase capacity factors, and reduce costs. This page describes the goal of WETO’s utility-scale wind technology research efforts and highlights some of its recent projects… Read more…

Energy Harvesting System Market Estimated to Experience a Hike in Growth By 2030 | Allied Market Research

The rise in demand for energy has increased dependency on fossil fuels for the production of energy. However, the use of fossil fuel for the production of energy leads to high carbon dioxide emission that further leads to environmental degradation. Hence, to overcome this problem, there is the development of energy harvesting techniques from building and urban infrastructure mainly roads. An annually large amount of energy in form of kinetic energy is wasted on roads. Thus, there are several developments in energy harvesting systems such as the use of solar panels, piezoelectric devices, and thermoelectric & electromagnetic harvesters in order to harvest energy from roads. This factor is predicted to augment the growth of the global market. Read more…

Energy Harvesting and Optimizations for Smart City

Energy harvesting and optimization are essential elements in the development of sustainable and smart cities. Energy harvesting is the process of transforming solar, wind, thermal, and mechanical energy into usable electrical energy. This energy can then be used to power smart city devices and systems, reducing dependency on conventional power sources, and reducing the city’s carbon footprint. Optimizing energy consumption is another crucial part of smart city development. Using data and analytics to identify places where energy is being wasted and executing strategies to reduce usage are required. Using intelligent sensors and automation systems to control building lighting and HVAC systems, for instance, can drastically reduce energy use… Read more…
