This paper deals with the theoretical and experimental study of an electromechanical system (EMS) actuated by a chemo-inspired oscillator, namely, the Brusselator oscillator. The modeling of such a system is presented. Theoretical results show that the displacement or flexion of the EMS undergoes spiking oscillations. This kind of oscillation is due to the transfer of the Brusselator electronic circuit signal to the mechanical arm. The theoretical results are confirmed by an experimental study with a good qualitative agreement.
