A new multifunctional composite material manufactured from vinyl-acrylic resin and mixed with battery waste powders containing graphite, manganese oxide, and zinc oxide particles has been developed. The battery waste (BW) was obtained from a recycling company as a byproduct from the grinding process of primary batteries (alkaline and zinc carbon batteries). In addition, 24 and 28 AWG copper wires (CuW) were obtained from recycling circuit waste, which were added in 5, 10 and 15 wt% contents to form composite materials, with all CuW of 2 mm length. These formulations were characterized using scanning electronic microscopy, compression, density, and piezoresistivity tests. When copper was added to the composite material, the behavior of the sensor was linear, a characteristic desired in piezoresistive sensors since they do not need any additional configuration to obtain said linearity. As the percentage of copper increased, the sensitivity of the sensor decreased and the conductivity increased.
