Leading cause of human death in most of country is roadway crashes. Supplemental restraint system playing vital role in preventing and protecting the passengers and drivers in case of accidents thereby providing chance of last line of defence against serious injuries. So there is need of sensor which sense the signals precisely with high sensitivity, low energy consumption and EMI insensitivity in harsh conditions which modifies the technology involved in present sensors used in automobile crash sensing. Work which is carried out here is designing structure of PhC stationed optical approach accelerometer sensor for supplemental restraint system or Airbag for vehicle passenger safety. Functionality of MOEMS device achieved through four free ends of slab is fixed and horizontal displacement of main slab using MEEP software for rods in air configuration. As the main slab displaces there will be change in spacing which alters the electromagnetic waves and which shift the transmission spectrum wavelength. Shift in wavelength of 0.001 for each micro displacement from 0 to 0.6 micrometre, prove the design methodologies and its validation. Interrelation between optical and mechanical system discussed here will measure the acceleration of vehicle. Q factor of 6000 observed for each submicron displacement representing accuracy level of proposed design for fabrication of device in future.
