Abstract: The Eastern Han Dynasty was a period of rapid development in science, technology and culture. The invention of Zhang Heng’s seismoscope is the most outstanding. The historical authenticity of the seismoscope, the material basis for the birth of scientific ideas, and the scientific contributions of Zhang Heng are briefly introduced. The seismoscope was an important intellectual inspiration for the creation of modern seismographs in the 19th century. The purpose of restoration research is to clarify the principles and structures of the seismoscope, to stimulate ideas and to contribute to the popularization of earthquake science. A presentation was made on the archaeological basis and scientific experimentation of the scientific restoration model.
