Flexible carbon nanotube composite sensors for medical device applications have been developed using small loadings of multi-walled carbon nanotubes dispersed into medical grade liquid silicone rubber for the purpose of measuring stress, strain and load placed on or by a medical device. The sensors may be attached to a medical device or molded within a medical device, such as an expandable balloon.
