I am a fourth year biomedical and mechanical engineering student and my final project has to do with designing a crash test dummy. The end goal is to mount the dummy on a bicycle and launch it at ~20kh/h, then it will be struck by an automobile driving at ~30km/h. Various different impact scenarios (side, rear, etc.) will be tested.
My task has to do with sensing/measuring the impact force, and the accelerations on the dummy's head. I have never dealt or learned anything about sensors so I am looking for some guidance on what sort of sensors I should be looking at. This project will have some small amount of funding so I clearly cannot go out and purchase $500 devices.
Right now I know that I will be concerned with the sampling rate as it must be able to measure and record the moment of impact. I have looked around and read that a gyroscope may be a good idea for acceleration measurement. I'm not quite sure what to look for in force sensors, however, the impact force may be somewhere around 4 kN.
If anyone could provide me with somewhere to start, either sensor reccomendations or something to read to help me understand what I should be looking for that would be great.
