Non-Contact Laser based Strain Sensing using Nano-Materials

Research and Impact:

Our group is the earliest to invent and develop strain sensing using nanomaterials–both contact and noncontact laser based–in an institute/center funded by NASA (Texas Institute of Intelligent Bio-Nano Materials and Structures for Aerospace Vehicles—co-principal investigator). Our team also conducted widely cited research on nanocomposite based strain sensing in the AFOSR funded study. We have recently developed and demonstrated laser based non-contact strain sensing with funding from Office of Naval Research.
