The technology introduces a new type of attachment to the shaft of a vibration motor designed to have the dual properties of eccentricity and an aerodynamic shape. This aerodynamic shape is intended to enhance the performance of the ERM-based device, improve its capabilities, or both. In this disclosure the term 'performance' means current draw, noise, or controllability of the aerodynamic vibration attachment. The aerodynamic vibration attachment may have additional properties such as an embedded or otherwise incorporated shape or target that facilitates the estimation or measurement of the aerodynamic vibration attachment's angular position, angular velocity, or both, by a sensor or sensors. Alternatively, the aerodynamic vibration attachment may have additional properties such as an embedded sensor or sensors, and facilitates the estimation or measurement of the aerodynamic vibration attachment's angular position, angular velocity, or both, compared to signals obtained from external, non-rotating sensors, targets, markers or references.
