We present a THz electromechanical meta-atom where the coupling between an electromagnetic mode and the displacement of a metallic micro-beam is substantially controlled by a conservative Coulomb force. Such system paves the way for the realization of coherent transducers from the terahertz to the optical domain and allows building and exploring fundamental optomechanical terahertz systems at room temperature.
