The aim of this paper is to study the materials that can be used for the impact detection and the force measurement in personal protective equipment. Several commercially available piezoresistive materials are investigated (EeonTex LTT-SLPA, Sefar Carbotex 03-120CF/03-160CF/03-205CF) and compared to proprietary DAid knitted piezoresistive fabric. It is demonstrated that the operating range of these materials can be extended by adding fiberglass mesh, which functions as a spatial separator and reinforcing layer, as well as by combining homogenous and heterogeneous materials in a single multilayer sensor. It is shown that EeonTex LTT-SLPA and Sefar Carbotex 03-120CF, used either separately or together, perform better than other studied materials. The derivative approximation can be used for more accurate signal analysis. The proposed solutions allow to increase the sensor operational range to a certain extent. A number of potential solutions is presented for the cases, when sensors are subjected to impacts that have substantially higher energy values.
