Wearable Actuators

Development of e-textiles and smart fabrics has broadened the applications of wearable actuators. However traditional actuators can't infuse more flexibility leading to the exploration and development of wearable actuators with novel nanocomposites and other materials including nanoparticles, polymers, ionic liquids. Integration of all these materials and their applications help in electrospinning, spray coating, weaving and solution casting.

Wearable Sensors

The low flexibility and consistency of traditional sensor systems in wearable electronics led to the use of nanomaterial-based sensors. Especially, 1D nanomaterials and nanocomposites including metallic nanowires and nanofibers are extensively used in the development of nano-material based wearable sensors. These sensors can be embedded in fabrics with the help of spin coating, vacuum filtration, dip coating and direct printing which can provide comfort to the users and also more flexibility.
