A simple electromechanical model is constructed in this work to investigate the dynamical behavior of a mechanical arm driven by a light-sensitive neural circuit, simulating the operation of a micromechanical device implanted in the brain under neuronal operation. The physical equation describing the relationship between neural firing and mechanical motion is provided, the dimensionless model is obtained using the scale transformation, and the Hamilton energy of the electromechanical system is calculated based on Helmholtz theorem. It is found that the variation of photocurrent, magnetic field and damping coefficient causes the neuron and mechanical arm to interact with each other to generate a variety of oscillations when the phototube is used as a voltage/current source. Furthermore, it is demonstrated that the conversion of field energy and mechanical energy is another effective method for estimating and controlling the oscillation modes of the electromechanical model. The results explain how a micromassager connected to a neuron processes information from both environment and itself, and provide an insight for the design of implantable neurostimulators to restore brain or muscle function.

This paper considers the experimental and numerical study of an electromechanical arm powered by a DC motor and subjected to the action of permanent magnets. The magnetic torques arise from permanent magnets mounted at the free end of the arm and along a circle. The electrical subsystem is powered by two forms of input signal (DC and AC voltage sources). For each case, we determine the condition for complete rotation of the mechanical arm versus the parameters of the system such as the arm length, the number of magnets, and the frequency of the external signal. The nonlinear dynamics of the system is examined by means of time-histories, bifurcation diagrams, Lyapunov exponents and phase portraits. Chaotic and periodic dynamics are detected numerically and confirmed experimentally.
