Mechanical properties of biomaterials

So, you know how different things like toys, clothes, and even food can feel different when you touch them or play with them? Like how some toys are soft and squishy and some are hard and bumpy? Well, materials that are used to make things inside our bodies also have different feelings and properties.

These materials are called biomaterials and they have to be strong enough to withstand the weight and pressure of our bodies, but also gentle enough so they don't harm us. Scientists and doctors use machines to test and measure these properties of biomaterials, like how much force they can handle before breaking or how much they can stretch without tearing.

These properties help scientists determine if a biomaterial is suitable for a specific use, like if it can be used to replace a bone or if it can be used to make a heart valve. So, just like you have different toys and clothes for different activities, our bodies need different biomaterials for different parts and functions.
