    Abstract—We present a biomimetic angular acceleration sensor inspired by the vestibular system, as found e.g. in mammals and fish. The sensor consist of a fluid filled circular channel. When exposed to angular accelerations the fluid flows relative to the channel. Read-out is based on electromagnetic flow sensing (pseudo Hall effect). The sensor is made out of two 3D printed parts which, when put together, form a channel and which allow for easy mounting of permanent magnets and electrodes to measure the flow induced potential difference. Experiments indeed show an acceleration dependent output voltage. However, we find strong contributions from other than electromagnetic sources which, due to their nature and magnitude, are interesting for further research.
