“…In the 1990s, the development of micro-gyroscopes and micro-accelerometers opened the possibility of the development of an artificial vestibule formed by microchips, including triaxial gyroscopes and accelerometers small enough to be used by a human being ( Gong and Merfeld, 2002 ; Liu and Shkel, 2003 ; Liu et al, 2003 ; Wall et al, 2002/2003 ; Alexandrov et al, 2004 ). Gyroscopes and accelerometers are now so sensitive that they can detect head movements in microgravity ( Sadovnichii et al, 2018 ). It is worth noting that recent advances in biomimetic SCC and otolithic organs development can improve the sensing capability of prosthetic devices, and because of their mechanical behavior, their output sensitivity and frequency selectivity will be analogous to natural systems producing a more reliable operation of prosthetic devices with less computational processing demand ( Raoufi et al, 2019 ; Jiang et al, 2022 ; Moshizi et al, 2022 ).…”

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.

This work discusses the challenges of space exploration, focusing on microgravity-induced physiological changes, particularly those affecting the vestibular system, which significantly alters human performance in space, necessitating effective countermeasures. In microgravity, astronauts experience disorientation and space motion sickness due to changes in vestibular input, leading to symptoms like vertigo and headache. Postflight, astronauts show various neurological changes, similar to symptoms in individuals with vestibular disorders experiencing significant cognitive and perceptual difficulties. Studies have also shown that microgravity affects cortical and sensory responses, altering perception, motor function, and brain connectivity. Galvanic Vestibular Stimulation (GVS) is explored as a countermeasure, using modulated electrical currents to evoke neuronal activity in vestibular end-organs, potentially stabilizing posture and gaze in microgravity. The work proposes that GVS could serve as a non-invasive intervention to help adapt to space environments by enhancing vestibular function and possibly aiding cognitive functions and underscores the need for continued research into the vestibular system’s role in human health and performance during space missions. It highlights the potential of GVS as a promising countermeasure for the challenges posed by microgravity.
