Our DEA team won the EAP In-Action Demonstration Award Finalist at the SPIE Smart Structures + NDE 2024
Soft Materials Research Laboratory has developed two distinctive electroactive polymers for haptic applications: a multi-line Braille display and a haptic device. The bistable electroactive polymer is stiff at ambient temperature, but highly compliant and stretchable...
Nanocomposite Scintillator
SMRL is collaborating with Prof. Arion Chatziioannou of Crump Institute for Molecular Imaging to develop a superfast scintillator for medical imaging and portal monitors. The new scintillator can detect X-ray and gamma ray with high light yield, nanosecond and faster...
SmartMat 2023 – Outside Front Cover Image
Dielectric elastomer actuators (DEAs) emerge as a soft actuation technology that exhibits such advantageous properties as large strains, fast responses, high energy densities, and mechanical compliancy. Extensive research over the past few decades has advanced the...
