New Road Safety Sensor Prototype Developed by Researchers

Researchers at the Centre for Nano and Soft Matter Sciences (CeNS) have created a special road safety sensor to improve safety at dangerous road curves where accidents often happen. This new sensor is made from a unique material that can both sense pressure and generate energy.

Development of the Prototype

The sensor uses a new kind of material called a polymer nanocomposite. This material can generate energy using the piezoelectric effect, which means it creates electricity when pressure is applied. The sensor is designed to be placed on movable ramps 100 meters before risky curves, giving oncoming vehicles visual signals, like lights, to alert them.

Material Composition

The key material in the sensor is a polymer nanocomposite. It is made by combining a base polymer, poly (vinylidene difluoride) (PVDF), with a special compound called vanadium disulfide (VS2). The VS2 gives the material a high surface charge, which improves its ability to generate electricity when pressure is applied. This makes the sensor more effective in gathering energy and sending signals.

Scientific Process

Making the Nanoparticles: The researchers first created tiny particles (nanoparticles) of VS2 to improve the piezoelectric performance of the sensor.

Creating the Composite Film: They mixed different amounts of VS2 into the PVDF polymer to create a film that has both pressure-sensing and energy-harvesting abilities.

Research Focus: The team studied how the surface charge of the nanoparticles affects the overall piezoelectric properties of the composite material. The more charge the nanoparticles have, the better the material performs.

Laboratory Demonstration

The researchers made a small version of the road safety sensor in the lab. It worked successfully as a pressure sensor, showing how it could be used in real-life applications. This prototype could also be used in future smart technologies.

Publication and Patent

The findings were published in the Journal of Material Chemistry A, and the researchers have applied for a patent in India. This means the technology has the potential to be developed for commercial use, and more research may follow to improve it further.
