antibacterial fabrics
by attaching nanoparticles of sliver to fabrics they can kill bacteria.these
these fabrics have lots of medical uses for example face makes
,and dressings. They can alsobe used to make anti-bacterial
toys and odour-free socks
integrated electronics are built in circuits
electronic devices can be incorporated intob a product design
this is know as integrated electronics
its commonly done in texile design ,where devices like mp3 players can be
incorated into things like clothing and bags .these devices are often operated with
quantum tunnelling composite swithes . these are washable and can so can be permanently attached to the product
other applicationjs include putting sensoers in clothes that monitornm heart
rate and blood pressure
