MEMS technology in head tilt monitoring after vitreoretinal surgery

Presented paper is focused on a new developing device intended for monitoring of patient’s head position during the post-operative period after vitreoretinal surgery. Keeping the head in an optimal position after this operation is crucial for optimal results of the recovery process. Head tilt monitoring is a complicated task during the normal life. Described device is based on a modern Micro-Electro-Mechanical Systems (MEMS) acceleration sensor. MEMS sensors are used for sensing gravitational acceleration. A microcontroller is used for data processing, logging and controlling user interface.
