Imagine a sensor chip that never sleeps, always listening for trouble inside wind turbine blades. Scientists just rolled out an acoustic sensor that detects cracks and erosion by picking up sound waves from inside the blade itself. For offshore wind farms, this could mean fewer risky trips for maintenance crews, less wasted material, and big savings. But does relying on 'always-on' tech create new vulnerabilities? Would you trust a chip to keep the lights on? #Tech #WindPower #SmartSensors
