Many developed and developing countries are using Nanotechnology in the fields of medicine, construction, and military. The advancements in Nanotechnology support the manufacture of wearable electronics which includes smartwatches, fitness trackers, smart garments, and so on.
Wearable electronics is the latest buzz word which deals with clothing and textiles that integrate computing devices like sensors, actuators, and power supply to perform effectively in the day-to-day lives of humans.
One of the key challenges in this wearable electronics technology is the requirement to achieve flexibility and user comfort. To attain this, researchers are making use of Nanotechnology with different materials like carbon nanotubes, graphene, polymers, and dielectric elastomers and composites.
How does Nanotechnology underpin wearable sensors?
Significance of Nanotechnology in wearables is highlighted by the contribution of Nanomaterial in the field of wearable electronics.
The 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.
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.
