Over the past several decades, a growing interest in better understanding the mechanical properties of biomaterials has been seen. Besides hardness and elastic modulus values that can be determined using indentation techniques, researchers and developers are also interested in knowing adhesion and scratch resistance of many types of surface coatings applied to these materials.
The scratch testing method is a suitable technique whose results can be used for improvement of lifetime and osseointegration of implants, stents or prostheses.
This application report demonstrates the use of the scratch technique for characterization of several biomaterials with Anton Paar Scratch Testers.

Radio wave weapon knocks out drone swarms
I hope they have assessed how easy it is to shield a drone against the attack. Hopefully the shielding would add too much weight.
