Abstract:
1. A vestibular prosthesis for a patient, comprising: one or more micro-electric-mechanical (MEMS) sensors, including at least one pair of gyroscopes in each of three orthogonal axes and at least one pair of accelerometers in each of the three orthogonal axes, to detect an angular and linear movement providing displacement measurements; at least one microprocessor coupled to the MEMS sensors, wherein the microprocessor uses a mathematical model of an informative process of a vestibular mechanoreceptor to produce an output comprising one of an electric pulse pattern and a continuous galvanic current pattern; a conditioning unit that amplifies and conditions the microprocessor output to apply current that is proportional to said output, to stimulation electrodes; wherein the microprocessor is configured to:
