The potential for a new sensor powered exclusively by sound is shaking up the world of battery-dependent devices. Swiss researchers from ETH Zurich have developed a patented technology that could replace millions of sensors worldwide, eliminating the need for batteries and the associated cost and labor of replacement. This breakthrough could also lead to customizable applications that can be activated or deactivated with a single word.
Traditional sensors used in industrial and medical applications rely on batteries for power, resulting in the frequent need for battery changes. This has hindered the widespread use of critical sensors, such as those used to monitor bridges for structural damage or retired gas wells for leaks. In the medical field, the situation is even more dire, with battery replacement surgeries required for implantable devices like pacemakers and anti-fibrillation devices.
The sound-powered sensor developed by the Swiss researchers offers a potential solution to these challenges. Made purely of silicone and free from toxic heavy metals or rare earths, the sensor activates when exposed to vibrations caused by sounds. By combining dozens of identically structured plates connected with tiny bars that act as springs, the sensor converts sound vibrations into electric current, eliminating the need for external power sources.
One of the most intriguing aspects of this technology is its ability to be programmed to react to specific sounds. For instance, a sensor could be designed to only respond to the distinct sound of cracks forming in a bridge’s structure, filtering out irrelevant noises. This principle can also be applied to recognizing different spoken words based on their sound energy.
Furthermore, the Swiss researchers have already filed a patent for an even smaller sound-powered sensor, opening up new possibilities for medical and other applications. These miniature sensors could be used in scenarios where battery-powered devices are currently impractical, such as monitoring eye pressure or creating sensors for biological functions.
While no sound-powered devices are currently on the market, the inventors are actively seeking commercial partners to bring their technology to fruition within the next few years. If no suitable partners are found, they are open to the possibility of establishing their own start-up.
The disruptive potential of sound-powered sensors extends far beyond the medical and safety industries. Industries are also expressing a keen interest in zero-energy sensors, seeing opportunities to reduce costs and improve efficiency.
The future of sound-powered devices that can be controlled with a single word or sound appears promising. With a three-year plan in place, the Swiss researchers are determined to make their innovative technology a reality. Whether through collaboration with industry partners or by founding their own start-up, they are committed to revolutionizing the sensor market and eliminating batteries from the equation.
