Penetration test of high-g micro acceleration sensor

A high-g piezoresistive acceleration sensor is designed in this paper.By applying to the projectile,the penetration tests are provided,which take the steel and concrete as a target.Experimental results show that the sensor has a good antioverloading ability in penetrating steel target.The measuring penetration overloading are analyzed in detail.The analysis shows that the penetration overload data of this sensor agrees with the 988 sensor.The beams of the sensor are fractured while penetrating concrete target and the further improvement should be made from the package.
