Performance of a passive device in improving tremor patients' handwriting capability

This paper provides the investigation of the performance One-Degree-of-Freedom system to be implemented in tremors patient writing device to reduce human hand tremor. The One-Degree-of-Freedom of two springs and a mass is proposed to absorb the hand vibration for patients that suffered tremors disease while writing. The performance of development device is based on drawing Archimedes spiral that done by a tremor patient.
