UD engineers use carbon nanotube composite coatings

A team of engineers at the University of Delaware is developing next-generation smart textiles by creating flexible carbon nanotube composite coatings on a wide range of fibers, including cotton, nylon and wool. Their discovery is reported in the journal ACS Sensors where they demonstrate the ability to measure an exceptionally wide range of pressure – from the light touch of a fingertip to being driven over by a forklift.

Fabric coated with this sensing technology could be used in future “smart garments” where the sensors are slipped into the soles of shoes or stitched into clothing for detecting human motion.

Carbon nanotubes give this light, flexible, breathable fabric coating impressive sensing capability. When the material is squeezed, large electrical changes in the fabric are easily measured.

Making it clear

For the past three years, almost 90 educators from around Delaware and Maryland have been working with scientists and environmental experts from the University of Delaware and the University of Maryland. The goal is to develop a richer understanding of climate change and build effective activities and instruction plans to help their students understand the data and find potential solutions.
