Abstract
In this contribution, we propose an energy-autonomous wireless sensor node for monitoring wind turbine blades. To allow a placement of the sensor node on the leading edge of the wind turbine blade with minimal influence to its performance, the electronics have to be ultra-thin and mechanically flexible. The concept of the sensor system is presented with a main focus on the eigenfrequency analysis of the rotor blade based on MEMS accelerometers. The sensor system is demonstrated on a small-scale wind turbine blade with a length of 1.07 m.
