Polydimethylsiloxane (PDMS) can be used for its optical properties, and its composition offers the possibility of use in the diverse environments (industry, photonics, medicine applications, security devices and etc.). Therefore authors of this article focused on more detailed working with this material. This material could be use for the sensory applications such as the sensor of pressure or weight, which may find use also in the field of security and defense. The article describes the process of making the prototype of the sensor and its verification based on laboratory results. Measurement methodology is based on the determination of the change of optical power at the output of the sensor prototype depending on the change in pressure or weight. We estimate the maximum load of the sensor on the basis of the laboratory results in the units of tons. Using a calibration measurement can determine the amount of pressure and weight with an accuracy of ± 2 %.
