Researchers Develop Soft, Stretchable ‘Jelly Batteries’ for Wearable Devices and Biomedical Implants

July 20, 2024

Researchers at the University of Cambridge have developed innovative soft, stretchable “jelly batteries” with potential applications in wearable devices, soft robotics, and even brain implants for drug delivery or treating conditions like epilepsy. Inspired by electric eels, these jelly-like materials feature a layered structure, similar to sticky Lego, enabling them to deliver an electric current.

The jelly batteries, reported in the journal Science Advances, are made from hydrogels: 3D networks of polymers containing over 60% water. These polymers are held together by reversible interactions that control the jelly’s mechanical properties. The ability to precisely control these properties and mimic human tissue characteristics makes hydrogels ideal for soft robotics and bioelectronics. However, achieving both conductivity and stretchability in such materials has been challenging.

Transforming Solar Panel Waste into High-Performance Lithium-Ion Batteries

July 18, 2024

Researchers at the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) have developed a groundbreaking method to recycle silicon from solar panels and repurpose it to create superior-performance lithium-ion batteries. This innovative approach is not only sustainable and cost-effective but also sets a new precedent for reusing solar panel components at the end of their life cycle.

The recent surge in solar panel installations marks a significant shift away from fossil fuels, contributing to a cleaner environment. However, it also foreshadows a looming waste problem, as these panels will reach the end of their operational life in about three decades, generating a massive amount of waste. Consequently, researchers worldwide are exploring viable roles for individual solar panel components. While metals like copper and silver will likely remain in high demand, repurposing abundant silicon has been a challenge—until now.

Autonomous Drone Traffic: ELTE’s Revolutionary Solution

July 17, 2024

After creating the world’s first self-organizing drone flock, researchers at Eötvös Loránd University (ELTE) in Budapest, Hungary have now demonstrated the first large-scale autonomous drone traffic system. This innovative system surpasses the capabilities of human pilots, showcasing a significant advancement in drone technology. The Department of Biological Physics at ELTE has been dedicated to group robotics and drone swarms since 2009. In 2014, they created the world’s first autonomous quadcopter flock with at least ten units. Now, their research group has achieved another milestone by publishing the dense autonomous traffic of one hundred drones in the journal Swarm Intelligence.

Flocking involves units synchronizing through coordinated joint movement, similar to a bird flock. In contrast, autonomous drone traffic involves drones with individual routes and goals, leading to potential conflicts, especially in open spaces where there are no designated routes. This scenario is akin to pedestrians crossing a square in various directions or drones flying freely in the sky.

Pioneering Brain-Inspired Memory Devices: The Nanofluidic Memristor

July 17, 2024

Memory, the ability to store information accessibly, is crucial for both computers and human brains. However, the methods they use to process information are quite different. The human brain performs computations directly on stored data, while computers must transfer data between a memory unit and a central processing unit (CPU). This separation, known as the von Neumann bottleneck, leads to increased energy costs for computers. For over 50 years, researchers have explored the concept of a memristor (memory resistor), an electronic component capable of both computing and storing data, akin to a synapse. Aleksandra Radenovic of the Laboratory of Nanoscale Biology (LBEN) at EPFL’s School of Engineering aimed for something even more ambitious: a functional nanofluidic memristive device that relies on ions rather than electrons and their oppositely charged counterparts (holes). This approach more closely mimics the human brain’s information processing and is more energy-efficient.

Revolutionizing Sneaker Production: The Birth of Lightspray

July 17, 2024

Inspiration can strike in the most unexpected ways. For On’s innovation team, it came from a hot glue gun on Halloween. Johannes Voelchert, a senior member of the team, watched a video where a crafter squeezed a thin filament of hot glue into a fluff of spider web. This sparked the idea of creating a shoe in a similar manner. Instead of dismissing it, the team at On embraced the idea with enthusiasm.

Four years later, what began as a one-person experiment expanded to a team of 20 designers and engineers at the Swiss footwear company. The result is Lightspray, a groundbreaking method in sneaker production. By placing a last (or foot form) on a robot arm, On can spray a shoe’s entire upper (its top part) from a single continuous filament in just three minutes.
