Researchers from Bahia Are Working on New Technology That Allows the Generation of Energy During the Walking Process. New Prototype May Arrive in the Coming Months.

Researchers from Bahia are studying the possibility of producing and collecting energy from the walking process. In this scenario, the simple movement of steps would become a renewable and clean energy source. The kinetic energy harvesting technology is being developed through a Federal University of the São Francisco Valley (Univasf), Juazeiro campus, led by Professor Helinando Pequeno de Oliveira.

Scientists from Bahia Want to Develop ‘Wearable Devices’ for Energy Harvesting from Walking

The project in Bahia studies how to manufacture wearable electronics with the aim of developing pieces that can collect energy from walking and transform it into electricity to charge electronic devices. Helinando emphasizes that the main goal of the research in Bahia is to produce a device that gathers energy from body movement.

The intent is for the triboelectric generator to capture energy from body movements and contact with clothing items like shirts, pants, and shoes. This energy will then be directed to power an energy storage device, such as a capacitor or supercapacitor, which in turn will provide the charge for electronic devices, making their operation independent of external recharging.

Prototype of Device capable of Generating Energy to Be Presented Soon

The project, which has partnerships with the São Paulo State University (Unesp), the Federal University of Pernambuco (UFPE), and the University of Araraquara (Uniara), is under development. The researchers from Bahia plan to present a prototype in the coming months.

According to the professor, the team is trying to arrive at a patentable wearable energy nanogenerator (TENG) soon. In addition to Helinando, the team includes André Luiz, Iuri Custodio, and Hermane Barud.

The State Secretariat for Science, Technology and Innovation (Secti) launched on National Science and Scientific Researcher Day, July 8, 2019, a series of reports on how Bahian researchers and scientists develop work in science, technology, and innovation to contribute to improving the quality of life of the population in important areas such as health, security, education, and others.

Other Advances in Energy Generation Through the Body

In addition to these advances in Bahia, the team of researchers from the University of Massachusetts Amherst in the United States developed a biofilm that can harness an energy source that had not been explored much until now: evaporation.

In summary, the researchers are able to generate clean energy from human sweat. The research team developed a biofilm that transforms moisture from the skin into energy, managing to generate continuous and stable renewable energy that can be used as an adhesive applied directly to the skin.

According to Xiaomeng Liu, a graduate student in electrical and computer engineering at the College of Electrical Engineering at UMass Amherst and the lead author of the article, this is very exciting technology and is truly clean energy, and unlike other sources called clean energy, its production is completely green.

Forget petroleum-based asphalt: a Scottish company transforms 684,000 plastic bottles into one kilometer of road that is 60% more resistant and up to 10 times more durable, and the technology has already started replacing traditional asphalt in more than 30 countries.

With billions in loans, China is rebuilding Nigeria’s railway network from scratch, abandoning the British colonial tracks that have turned to scrap and creating a corridor of over 1,300 km to take the load off the roads of Africa’s largest economy.

Study solves great ancient mystery: remains of Philip II, father of Alexander the Great, are identified in Vergina and resolves the enigma of the Macedonian royal tombs that had lasted half a century.

Australia prepares to dredge 96.5 million m³ in Moreton Bay to deepen, widen, and realign channels of the Port of Brisbane, in a project of up to 25 years designed to accommodate larger ships and enhance maritime safety and regional port efficiency.

Larger than the Toyota Hilux and with a towing capacity of 3.5 tons, the new MG U9 2026 features a 2.5 turbodiesel engine, 520 Nm, 4×4 traction with three locks, and an almost full-size build.

Portugal installs two giant underwater sockets to draw water from the Atlantic and create a €107.9 million desalination plant in the Algarve capable of producing 43.2 million liters of potable water per day with ocean intake 2 km from the coast.

Minha Casa Minha Vida for the elderly: the 80-year rule can double financing installments; see rules and age limit

Giant geotextile bags filled with sand have become flexible barriers against erosion in America, Europe, Asia, and Oceania; the technology replaces tons of concrete and rock with permeable tubes that dissipate waves and protect beaches, dunes, and riverbanks.

More than 500 Marines, robots, drones, and armored vehicles are deployed in Rio de Janeiro for the UN to certify Brazil at the highest level of readiness for peacekeeping missions. It is the first force in the country to achieve this status in all of history.

A large part of the Netherlands lies below sea level and remains dry only because an invisible machine of dikes, pumps, and giant gates works nonstop, a system born from the tragedy of 1953, when the North Sea invaded the country and killed 1,836 people.

It seems simple, but it generates electricity: scientists transform ambient humidity into electricity with gelatin and salt, and the generator still works for more than 30 days.

Soon, smartphones may be able to “see” objects hidden behind walls with LiDAR.

The world could operate on clean electricity by 2050, but a study indicates that this would require up to 20 TW of renewable energy, more than 9 million hectares for solar, and strong cooperation between countries.

For the first time in France, solar electricity will power metro trains without going through the public grid. The pioneering Rennes project will begin construction in June with 6,000 square meters of solar panels, and users themselves can invest and earn a 5% annual profit.
