The field of material science have been advanced through the past decades. We can prove it if we observed the infinite types of things we used and the properties they involve. The demand of light and stronger materials has motivated engineers to create multifunctional materials (including sensing, actuation, electromagnetic shielding,etc)
I have recently read an article about a prototype of a human hand that have been made of SMA wires. (SMA means Shape Memory Alloys). The design of this hand is mature. It is mobile and adaptable and the interaction between muscles, ligaments, tendons, nerves and bones represents a huge tool.
Some universities like the University of Utah has developed this hand and it shows a very soft movement and good efficiency.
The world of materials is helpful and intersting. If we are eager to know more about this world, for sure we can be incredible inventors and creators of new needs.
