The threat of human-caused climate change looms large, prompting the need for revolutionary solutions to protect the environment. However, amidst this crisis, nature continues to inspire technological advancements that offer promising alternatives. Evripidis Gkanias, a researcher from the University of Edinburgh, believes that nature’s solutions, developed over billions of years, hold immense value in educating artificial intelligence. While human creativity is remarkable, it pales in comparison to nature’s robustness, which engineers recognize. This article explores a selection of this year’s cutting-edge nature-based technologies, from light-detecting compasses to water-collecting webs and inflatable robots.
The sun serves as a crucial reference point for certain insects, like ants and bees, who rely on the intensity and polarization of sunlight for navigation. Researchers sought to replicate their eye structure and created a compass capable of estimating the sun’s location in the sky, even on cloudy days. Unlike traditional compasses that depend on Earth’s weak magnetic field, this innovation remains unaffected by electronic interference. Gkanias, the lead researcher, expressed optimism about the prototype’s success and envisioned transforming it into a compact and lightweight product, easily accessible with the right funding. Additionally, this insect-inspired compass could be adapted for use on any planet with a visible celestial light source.
Regions grappling with water scarcity may soon find hope in fabric inspired by spider webs. By studying the feather-legged spider’s intricate “spindle-knots,” researchers discovered a way to fabricate threads capable of collecting drinking water from morning mist. Once this material can be mass-produced, the scale of water harvesting applications could be considerable. Yongmei Zheng, one of the study’s authors, emphasized the potential impact of this innovation in combatting water scarcity in vulnerable regions. Nature’s inspiration, in the form of spider threads, might offer a sustainable solution to this pressing issue.
Inflatable Robots: Emulating the Growth of Vines
Taking inspiration from the way vines creep and stretch, scientists at the University of California, Santa Barbara developed an inflatable robot that “grows” towards light or heat sources. These robots can navigate using fluid-filled pouches instead of expensive electronics and could potentially locate and extinguish smoldering fires, reducing carbon emissions. While these robots are currently slow, Charles Xiao, a co-author of the study, emphasized their suitability for addressing specific fire types. However, before they can be deployed effectively, the robots need further development to improve their heat resistance and agility.
Drawing inspiration from slimy kombucha mats, a team of scientists at the Unconventional Computing Laboratory at the University of the West of England in Bristol has created “kombucha electronics.” By printing electrical circuits on dried kombucha mats, the researchers successfully illuminated small LED lights. These mats, possessing properties similar to textiles and leather, are sustainable, biodegradable, and can withstand immersion in water without being destroyed. The authors envision a future where “kombucha wearables” seamlessly integrate sensors and electronics, enabling unobtrusive technology integration with the human body. However, durability and mass production remain significant challenges to be overcome.
Pangolin-Inspired Robots: Revolutionizing Internal Medicine
The pangolin, with its unique appearance reminiscent of a cross between a pine cone and an anteater, has inspired the development of a tiny robot for potentially life-saving purposes. By studying the pangolin’s ability to curl up in a ball for self-protection, researchers aim to create a robot that can navigate the human digestive tract, unfurl, and deliver medicine or stop internal bleeding in hard-to-reach areas. The pangolin’s structure presents the ideal combination of softness, which won’t harm the human body, and hardness, facilitating conductivity. Although these tiny robots are in the early stages of development, they hold immense promise, with cost estimates as low as 10 euros per unit.
The remarkable innovations discussed in this article highlight the power of nature’s influence on technology. From compasses mimicking insect eyes to water-collecting webs, inflatable robots, kombucha electronics, and pangolin-inspired robots, these creations demonstrate the potential for combining natural design principles with human ingenuity to solve complex challenges. As the world grapples with environmental crises, finding inspiration in nature’s time-tested solutions offers a ray of hope for a sustainable and resilient future. Through continued exploration and adaptation of nature’s offerings, we can strive towards a harmonious coexistence between technology and the environment.
