A flexible sheet of aligned carbon nanotubes includes an array of aligned nanotubes in a free standing film form not adhered to the synthesis substrate, with a matrix infiltrated interstitially into the nanotube array with access to the nanotube tips from both the top and bottom. That is, the infiltrant is purposely limited from over-filling or coating one or both exterior top and/or bottom surfaces of the array, blocking access to the tips. A typical matrix is a polymer material.

In this paper, polydimethylsiloxane (PDMS), carbon nanotubes (CNTs), and zinc oxide (ZnO) were combined to create functionalized piezoresistive and piezoelectric sensors for pressure sensing and energy harvesting. Samples were foamed to show that the increased deformability of the foam sensors makes them suitable for a range of applications including dexterous robotics, tactile sensing, energy harvesting, and biosensing. Uniform dispersion of CNTs was achieved with chloroform as the solvent. Samples were foamed using chemical blowing and scaffolding but granulated sugar at 70% porosity resulted in foamed samples with the most consistent mechanical properties. Samples underwent tensile and compressive testing for their …
