Imagine a battery that you could actually eat! In 2023, researchers in Italy developed a rechargeable battery made entirely from edible materials. It uses ingredients such as vitamin B2, quercetin, seaweed and beeswax. The invention could one day be used to power tiny medical devices that work inside the human body or sensors used to check food quality. A newer version presented in 2024 was even powerful enough to operate a small Bluetooth device. Batteries for breakfast, anyone?
THE WATER-FROM-AIR MACHINE
Getting drinking water from thin air may sound impossible, but researchers are making it a reality! In 2024, engineers at the University of Utah developed a compact device that captures water molecules from the air, even in dry conditions. The machine uses special materials to collect moisture and heat to turn it into liquid water. Technologies like this could eventually help provide fresh water in places where water is difficult to find. Who needs rain?
THE BIONIC HAND
Science fiction is getting closer to real life! In 2023, researchers presented an advanced bionic hand that connects directly to a person's bones, muscles and nervous system. The user can control the artificial hand using signals from their own body, while the system can also provide sensory feedback. The technology was designed to make a prosthetic hand feel and behave more naturally during everyday life. A real-life robotic hand? Almost!
THE SMART SOLAR WINDOW
What if your windows could help power your home? In 2025, researchers developed a new type of smart window that combines semi-transparent solar technology with a thin layer of flowing water. The window can produce electricity while also absorbing some of the heat that would normally enter a building. The heated water could even be used for hot-water needs. In the future, windows may do much more than simply give us a view!
