What is it about?
This work shows the design and assembly of a machine for tensile testing of polymers, especially industrialized paper type A4 used for deposition of fine graphite films obtained from pencils. The mechanical stresses, deformations and the modulus of elasticity of the fabricated specimen are analyzed.

Why is it important?
This paper proposes an experimental technique to identify and characterize the elasticity modulus of A4 paper to be used as a substrate for the deposition of piezoresistive graphite films according to ISO1924- 2:2008.
Perspectives
The experimental value of the Young's Module for paper, obtained in this paper, is close to the value available in the literature. However, this is critical for the design of piezoresistive graphite sensing elements and their production in large quantities. The value obtained was found under laboratory temperature and humidity conditions this is important when designing sensor devices using flexible polymeric paper substrates.
