Nanomechanical Testing Technology

Indian scientists in collaboration with two international institutions developed a novel method. Nanomechanical Testing Technology..

Why In News?

  • Indian scientists in collaboration with two international institutions developed a novel method to test nanomechanical properties of materials at very minute scales with high precision and accuracy.

What is Nanoindentation Technique?

Nanoindentation is a materials testing technique used to measure mechanical properties such as hardness, elastic modulus and other material responses at very small scales, often on the order of nanometers. 

The technique involves applying a controlled and localized force to a material’s surface using a sharp indenter, typically a diamond tip, and then measuring the resulting depth of penetration.

The nanoindentation technique is particularly valuable for studying materials at the micro- and nanoscale, where traditional macro-scale mechanical testing methods are not suitable or accurate.


  • It has been widely used to measure the strength of semiconductor devices and structural materials that have ubiquitously penetrated every aspect of our daily life through electronic gadgets. 
  • It has been used for a wide range of applications from identifying cancerous cells to establishing how meteorites are formed in deep space.
  • The novel approach involved a combination of extensive modelling and simulation to understand the material response during an indentation test and subsequent tailoring of the methodology to improve the precision and accuracy
  • The modelling results have also been validated by experiments under extreme conditions. 

Relevance of Latest Development 

  • The new methodology not only significantly improves the precision and accuracy of what is known as nanoindentation technique or testing of mechanical strength, but enables testing at much higher rates, thus facilitating high throughput.
  • The new methodology is expected to impact a broad spectrum of scientific research on measuring the strength of materials at small scales.
