Material testing device (9) for performing indentation measurements, the material testing device (9) defining an axis (z) and comprising: - a support element (6) adapted to permit the material testing device (9) to be attached to a test rig (21); - a test tip (1) adapted to be brought into contact with a solid sample; - an actuation device (3) comprising an active material (20), the actuation device (3) being disposed between the support element (6) and the test tip (1), the actuation device (3) further being adapted to displace the test tip (1) in at least one direction comprising a component perpendicular to said axis (Z) by reaction of the active material (20) to an applied stimulus. According to the invention, the actuation device (3) is further adapted to act as a force sensor so as to be able to sense a force applied by the test tip (1) on the solid sample by means of measurement of a response of said active material (20) to application of said force. |
