VOCSENSOR uses hybrid materials to manufacture sensors for volatile organic compounds (Hybrid Materials for Low Cost Organic Volatile Compound Sensor System). Its aim is to manufacture a device to monitor in real time the concentration of the so called Volatile Organic Compounds (VOCs). The detector has been conceived as a low-cost portable device highly-sensitive to VOCs. Equipped with wireless communications (together with IoT devices), it will have a display application and an alert management system installed in a mobile terminal (Smartphone or tablet).

The VOCSENSOR consortium has four partners for all the aspects of the product cycle: National Taiwan University, Szeged University (Hungary), the Nordic company NanordicOy and Envira Sostenible.

The sensor element is based on a hybrid polymer whose absorption coefficient in a certain wavelength range may change depending on the type and concentration of VOC to which it is exposed. This feature, together with adequate electronics of control and process of the electro-light signal and a system for storage, communications and management of alerts, enables this consortium to manufacture and market (in a short period of time) a reliable low-cost VOCs detector.

Nowadays the first prototype of this device is in its final step and high concentrations of VOCs have already been detected. In coming years, with the improvement in the sensor compound, its selectivity and capacity to detect low concentrations will greatly improve so it will be possible to apply it in industrial and domestic devices.
