At the University of Saarland, professors Stefan Seelecke and Paul Motzki are leading research that could revolutionize pump and valve design, following an innovation based on the use of ultra-thin silicone elastomeric films , which allow for a reduction in the size, weight, and energy consumption of the devices.
Technology based on ultra-thin elastomeric films
Pumps and valves require motors to generate a vacuum or control the flow of liquids , which entails high energy consumption and constant maintenance. However, the technology developed by the Saarland research team represents a “major technological leap.”
[post_relacionado]However, the design of pumps and valves based on dielectric elastomers does not require external motors, which reduces their size and weight while increasing their energy efficiency. Furthermore, the technology allows for continuous operation without the use of compressed air, making it quieter and suitable for highly demanding environments.
According to Professor Paul Motzki, Scientific Director of ZeMA , these valves based on dielectric elastomers consume up to 400 times less energy than pneumatic valves. The technology developed by the Saarbrücken team has a range of applications beyond vacuum pumps .
Such devices can be used in haptic feedback systems , robotic grippers , smart textiles , and other systems requiring high-precision actuators. The pumps and valves are self-sensing, meaning they can monitor their own operation and detect problems such as blockages or vacuum failures.
Furthermore, the team has demonstrated that it is possible to increase both pressure and flow rate by connecting the actuators and pump chambers in parallel or series configurations. This modular approach allows the technology to be adapted to a wide range of industrial applications. With the help of mateligent GmbH , a company established to transfer research to commercial applications, the team plans to bring this innovation to mass production in the coming years.
Dielectric elastomer technology is opening up new possibilities for a wide variety of sectors, from biotechnology to robotics . Their energy efficiency, low manufacturing costs, reduced noise, and reduced maintenance make these devices an attractive option for industry.
