The present invention describes a vestibular prosthesis that includes micro-electro-mechanical sensors (MEMS); gyroscopes of each sensitivity axis (X, Y, Z), accelerometers on each sensitivity axis (X, Y, Z) to detect an angular and linear movement that provides displacement measurements; gyroscopes in each of the axes of space (X, Y, Z); a microprocessor connected to MEMS sensors and producing a pattern of electrical pulses or a pattern of direct galvanic current; a conditioning unit that amplifies and conditions the output of the microprocessor to apply current to the stimulation electrodes; The microcontroller is configured to: determine the displacement of the dome and the otolithic mass; determine a membrane potential as a result of a displacement detected by MEMS sensors by determining a transduction current; and determine a pattern of discharge of afferent neuron action potential, which synapses with the hair cell by means of a mathematical model of the informative process in the mechano-receptor-vestibula r. |
