Design and implementation of MOEMS based optical diaphragm using Photonic Crystal for the prevention of barotrauma

When there is stress on the eardrum because of a change in air pressure is known as Barotrauma. If there is excessive pressure than 20 KPa, damage to the eardrum may occur. During air travel, Barotrauma can occur due to pressure differences at high altitudes. This paper presented a MOEMS based press...
