Biohybrid actuators consisting of skeletal muscle and artificial lattice possess unique features such as self-growth and self-repair functions. As a first step in developing a model-based design for biohybrid actuators, we used the existing muscle contraction model to propose a design method that can achieve appropriate performance for muscle specification. Utilizing the actual skeletal muscle of the toads, muscle contraction force under multiple square waves with different frequencies and amplitudes are used to determine the model parameters by fitting them to the simulated forces. Based on the results, the relationship between the muscle specification and the model parameters is obtained, and we successfully designed muscle specification required to generate specific contraction force based on this model.
