This study presents a smart pen prototype designed to dynamically mitigate hand tremors, thereby enhancing writing quality and user comfort for individuals with conditions such as Parkinson’s disease.

After the ISA converges, the rotor vibration amplitude Vin is gradually reduced. in V drops from 11.74 um to 2.70 um, decreasing by 77.0%. Performing FFT analysis to the rotor displacement, the 1st ...
