Transforming Infrastructure Sensors

SENTINEL is implementing piezoelectric sensor technology for the precise detection of vibrational excitations in pipes, ropes, and bars, with remote information gathering capabilities. This approach allows for the continuous and non-intrusive monitoring of these structural elements, providing critical insights into their dynamic behavior.

By strategically placing piezoelectric sensors, we can capture subtle variations in vibration patterns that may indicate changes in structural integrity or operational performance. The remote data acquisition system enables real-time monitoring and historical analysis, allowing for proactive maintenance and early detection of potential issues.

1

Non-Invasive Detection

Signals generated by very sensitive piezo sensor assemblies, secured to metallic elements, allow space localization of excitations and defects. Light percussive excitations — signal amplitudes of few hundred millivolts.

2

Remote Transmission

Signals shaped as clean pulses feed an RF transmitter that transfers information to a remote receiver — allowing remote analysis of the information collected on metallic elements. Arrays can cover tens of kilometers.

3

Real-Time Network Control

Setting up arrays of sensors for controlling in real time the status of pipe networks. Particularly valuable for oil & gas pipeline security — detecting fraudulent holes, avoiding environmental disasters.

Scientific Foundation

SENTINEL technology is based on peer-reviewed research published in Sensors (MDPI, 2024): "Detecting Excitations of Pipes, Ropes, and Bars by Piezo Sensors and Collecting Information in Remote" — Cirillo, Reali & Soda, Pipe Monitoring Corporation (PIMOC), Rome.

The research demonstrates signal voltage amplitudes of ~300 mV generated by piezo sensors as a result of very light percussive excitations. Low power required for transmitting data, and low cost of the sensing and transmitting assembly.
