“…An additional aspect of developing a vestibular prosthesis is the concept of a transfer function that converts the sensor output into an adequate stimulation pattern for vestibular afferent neurons. Most authors have used a linear or sigmoidal transfer function to code the gyroscope output as a frequency-modulated output ( Gong and Merfeld, 2002 ; Della Santina et al, 2005 , 2007 ; Töreyin and Bhatti, 2013 ; Perez-Fornos et al, 2014 ; Boutros et al, 2016 ; van de Berg et al, 2017a ). A neuromimetic mathematical model to code the gyroscope or accelerometer output into a series of frequency-modulated pulses has been proposed ( Sadovnichy et al, 2007 ; Vega et al, 2008 , 2016 ; Alexandrov et al, 2014 ).…”

“…The most advanced version of the multichannel vestibular prosthesis (MVP-2a) was designed based on an applicationspecific integrated circuit (ASIC) which included a multiplicity of electrodes (sixteen) in a highly integrated system (Hageman et al, 2016). Tests of this device in an implanted monkey showed that eye movements in the expected plane with gains from 0.04 to 0.33 were obtained.…”

Balance disorders are highly prevalent worldwide, causing substantial disability with high personal and socioeconomic impact. The prognosis in many of these patients is poor, and rehabilitation programs provide little help in many cases. This medical problem can be addressed using microelectronics by combining the highly successful cochlear implant experience to produce a vestibular prosthesis, using the technical advances in micro gyroscopes and micro accelerometers, which are the electronic equivalents of the semicircular canals (SCC) and the otolithic organs. Reaching this technological milestone fostered the possibility of using these electronic devices to substitute the vestibular function, mainly for visual stability and posture, in case of damage to the vestibular endorgans. The development of implantable and non-implantable devices showed diverse outcomes when considering the integrity of the vestibular pathways, the device parameters (current intensity, impedance, and waveform), and the targeted physiological function (balance and gaze). In this review, we will examine the development and testing of various prototypes of the vestibular implant (VI). The insight raised by examining the state-of-the-art vestibular prosthesis will facilitate the development of new device-development strategies and discuss the feasibility of complex combinations of implantable devices for disorders that directly affect balance and motor performance.
