1. A laboratory rodent sensor helmet comprising:
a flexible substrate conformed to fit a head shape of a life size adult rodent's head and provide even pressure distribution to said rodent's head that will permit concussion to said rodent without overt pathology, said substrate having a first side and a second side;
sensor films mounted on said first and said second sides of said substrate configured for measuring direct projectile impact force, wherein said sensor films measure pressure distribution and magnitude on an outer surface and on an inner surface of the helmet and wherein the helmet protects said rodent's head against skull fracture;
wherein said substrate is about 0.91 mm thick and the sensor films are about 0.18 mm thick.
