Modern buildings are increasingly evolving beyond mere physical spaces for living or working. They are becoming complex ecosystems where security, communication, and convenience are tightly intertwined and digitally managed.

In response to these shifts, new solutions are emerging that do not merely secure access but integrate seamlessly with smart installations to simplify the daily lives of their users. The CODI LINEA AZZURRO product line, developed by Grupa Techniczna CODI Jacek Rydzewski, exemplifies this trend by combining advanced electronics with a practical approach to the needs of modern residential and commercial developments. These products demonstrate how security technology can become a native component of a smart building rather than just a technical add-on.

The CODI LINEA AZZURRO line represents technologically mature solutions in the fields of security and building automation, meeting the rising demands of high-end real estate investments. The systems developed by Grupa Techniczna CODI Jacek Rydzewski include video intercoms, communication interfaces, and monitors that pair high-quality craftsmanship with advanced smart building integration features.

Equipped with HD cameras and remote management modules, the video intercoms provide effective access control and real-time entry monitoring, regardless of the time of day.

The system is further enhanced by communication interfaces supporting Bluetooth and voice communication, allowing for a seamless exchange of data between devices and the building's digital infrastructure. The entire suite has been designed with IoT compatibility and building automation in mind, making the CODI LINEA AZZURRO line a scalable tool ready for implementation in international markets. These products compete not on price alone, but on functional value, reliability, and aesthetics—factors that are paramount in the modern and premium construction segments.

Revolutionary Cold Plasma Technology

At the heart of the project lies a novel technology: self-disinfecting surfaces activated by cold plasma. This innovation integrates two seemingly conflicting functions — capacitive touch keyboard functionality and a dielectric barrier discharge (DBD) plasma generator. The user interacts with the panel as they would with any standard touch interface; however, once the interaction ends, an automatic disinfection cycle is initiated.

Technical Implementation and Design

The design employs a multilayer metal-ceramic composite (LTCC), enabling the generation of an electric field of several tens of kV/cm, without the risk of electrical breakdown or shock. A key challenge was to develop an electrode and dielectric system capable of operating in both touch and plasma modes.

For this purpose, a programmable high-voltage power supply with leakage and breakdown detection was designed, which cuts off voltage within fractions of a second in case of anomalies — ensuring full user safety.

Advanced Electronics and Control Systems

From an electronics perspective, the challenge lay in integrating traditional transistor driver functionality of the HV converter with low-level operational monitoring — including leakage current measurement, breakdown detection, and dynamic power shutoff.

Patent Protection and Innovation

This solution has been submitted for patent protection. Its innovation stems not only from using plasma for disinfection but especially from integrating this function with a conventional touch interface within a single electrode structure.

Previous disinfection methods, such as UV-C systems, are expensive, difficult to miniaturize, and come with significant safety and material degradation limitations. In contrast, cold plasma is safe for users, energy-efficient, and fully integrable with existing systems.

Commercial Implementation and Applications

It is worth noting that the project was implemented under the "Fast Track" program of the National Centre for Research and Development and was designed from the outset for practical implementation — both as an OEM solution for manufacturers of public-use equipment and as an upgrade component for existing infrastructure.
