Self-sensing technology

Micropump monitors itself and detects anomalies without additional external sensors
Many analysis and processing tasks in medical technology, biotechnology and the chemical industry require the handling of extremely small quantities of liquids. The precise dosing of liquids or gases is a challenging task. This is why micropumps are used for these dosing tasks.

To ensure high dosing accuracy and reliability, it is important to monitor possible malfunctions and failures. One of the main disturbance variables in micro dosing technology are small gas bubbles, which are unavoidable in practical operation. These disturbances can lead to dosing errors or even jeopardize patient safety during medication dosing if the required amount of medication is not dosed correctly.

Revolutionary self-sensing technology for a self-monitoring micropump
The Fraunhofer Institute for Electronic Microsystems and Solid State Technologies (EMFT) has developed a self-sensing technology based on our micropumps, which has been integrated into the pump. This results in innovative solutions that offer unique advantages for numerous applications. Our self-monitoring micropump detects dosing anomalies and faults, such as bubble formation, without the use of additional external sensors. Thanks to the integrated self-sensing technology, the dosing system can monitor its own status in real time.

AI detects gas bubbles - A new dimension of precision
The integration of artificial intelligence (AI) enables our self-monitoring micropump to reliably detect gas bubbles and their size. By evaluating the control signal of the micropump using AI and the piezo effect, the pump can react precisely and in good time to any gas bubbles that occur. This groundbreaking development represents a new dimension of precision in dosing and offers increased safety during use.
