Abstract
A sensing material for use in a sensor is disclosed. Such a sensing material includes a polymer base and a piezoresistive nanocomposite embedded into the polymer base in a continuous pattern. The nanocomposite comprises a polymer matrix and a plurality of conductive nanofillers suspended in the matrix. The conductive nanofillers may be one or a combination of nanotubes, nanowires, particles and flakes. The density of the plurality of nanofillers is such that the nanocomposite exhibits conductivity suitable for electronic and sensor applications.

A method for forming a sensing material, comprising:
- adding a polymer matrix into a first organic solvent solution and allowing the polymer matrix to dissolve;
- dispersing a conductive nanofiller into a second organic solvent solution and stirring;
- adding the first organic solvent solution to the second organic solvent solution, forming a mixture, and stirring the mixture;
- evaporating the first and second organic solvent solutions from the mixture;
- and
- adding a polymer curing agent to the mixture, forming a conductive nanocomposite, embedding the conductive nanocomposite into a polymer base in a continuous pattern to form the sensing material.
