A novel electromechanical system is devised to mimic the intricate control of muscle activities by the nervous system. This system integrates a neural circuit with a moving beam and incorporates a phototube and a thermistor to detect and respond to variations in light and temperature. The output current from the circuit subjects a current-carrying coil to Ampere's force within a magnetic field, actuating the movement of the connected beam. The effects of light and temperature on the electrical activity of the neuron and the oscillation of the beam are investigated through bifurcation analysis and energy evolution. It is observed that the moving beam effectively replicates the behavior of electrical signals, and the system undergoes mode transitions from periodic to quasi-periodic states. Furthermore, the injection and conversion of energy serve as an effective means for modulating oscillations, providing a new perspective on the dynamic control of the system. These results suggest the feasibility of using electromechanical systems to simulate real muscles and indicate the controllability of the oscillation state through specific signals.
