We present an experimental model for a semicircular canal with canalithiasis. Canalithiasis is a pathological condition where free-floating particles disturb the flow field in the semicircular canals. This model is designed to mimic the natural flow field in the semicircular canals, allowing for the study of the effects of canalithiasis on the vestibular system. The model consists of a semicircular canal with a diameter of 1 mm, filled with a fluid that mimics the properties of the endolymph. The fluid is stirred by a small motor, creating a flow field that is similar to the natural flow field in the semicircular canals. The model is designed to be used in conjunction with a microscope, allowing for the observation of the flow field and the effects of canalithiasis on the vestibular system. This model has the potential to provide valuable insights into the mechanisms of canalithiasis and the effects of the condition on the vestibular system.
