The aim is to fabricate the bio-actuator mimicking the skeletal muscle tissue and to assemble a microrobot. The bio-actuator is made by assembly of modular fibers with magnetic ends, which are for the manipulation of the fibers including culture with stretch, mechanical properties evaluation, and assembly of fibers.In 2022, to achieve the assembly of the modular fibers, I focused on the fabrication of muscle fibers with magnetic ends, and evaluation of the mechanical properties of fibers. By selecting the magnetic nanoparticles, the max magnetic force reached 3 mN, which satisfied all of our manipulation .And I succeeded the monitor of young's modulus change of the msucle fiber by switch between the systems for culture with magnetic stretch, and tensile experiment with magnetic fixation.

其目的是制造模仿骨骼肌组织的生物致动器并组装微型机器人。生物致动器是由带有磁性末端的模块化纤维组装而成，用于纤维的操作，包括拉伸培养、力学性能评估和纤维组装。2022年，为了实现模块化纤维的组装，我专注于带有磁性末端的肌肉纤维的制造，以及纤维的力学性能评估。通过对磁性纳米粒子的选择，最大磁力达到3mN，满足了我们的所有操作要求，并成功地在磁性拉伸培养和磁性固定拉伸实验的系统间切换，实现了对纤维杨氏模量变化的监测。
