An innovative piezo goniometer that fully fulfils all the requirements for the channeling experiment in the LHC is presented. The piezo rotational stage is based on a specifically designed flexural structure with closed loop position control using a high accuracy interferometric angular sensor. The design guidelines as well as the experimental validation results are also presented.
