A "Test Dummy" is a model used in various fields, primarily in automotive safety testing. These dummies simulate human bodies to assess the impact of crashes on passengers. They are equipped with sensors to measure forces and movements during tests, helping engineers improve vehicle safety features. In addition to automotive applications, test dummies are also used in medical research and product testing. For instance, they can help evaluate the safety of new medical devices or equipment. The data collected from these dummies is crucial for developing standards and regulations to protect human lives in real-world scenarios.
