Vibration sensing and control in structures and machinery are essential to prevent damage or failure. This paper proposes a new sensor, based on polymeric materials, to be used as a vibration sensor. Ionic polymer metal composites (IPMCs), active materials showing a bidirectional electromechanical coupling, are used. A new model has been developed and a test setup was realized using an electromechanical...
Ionic polymer metal composites (IPMCs) are active materials that exhibit interesting bidirectional electromechanical coupling phenomena: by bending an IPMC strip a voltage output is obtained, while a voltage input is able to cause the strip to bend. They are of increasing interest in innovative applications due to several advantages respect to competing technologies (SMA, piezoelectric, etc.), such...
