"Revolutionizing Sensor Technology: Harnessing Sound Waves to Eliminate Batteries"
Researchers have developed a new type of mechanical sensor that harnesses vibrational energy from sound waves to power electronic devices, eliminating the need for batteries. The sensor, made of silicone and metamaterial, can distinguish between specific words or sounds and trigger electrical pulses to activate devices. Potential applications include infrastructure monitoring for earthquakes and building cracks, as well as detecting gas leaks in decommissioned oil wells, offering a sustainable and cost-effective alternative to battery-powered sensors.
