Pressure-controlled micro-membrane mirror for endoscopical applications
Pressure-controlled micro-membrane mirror for endoscopic applications: the use of micro system technologies allows the manufacture of various micro-mirror devices for endoscopic applications. Micro mirrors are fixed onto elastomeric membranes and are capable of changing angular or translational positions by pressure variations. While common systems operate electrostatically by means of health-concerning high voltages, the use of a pressure controlled actuator presents no health risks and can therefore be used in vivo. Furthermore, the mirror deflection covers a wider angular and translational range compared to state-of-the-art products. Micro-membrane mirrors can also be arranged into arrays and selected parts thereof can be controlled individually.
