Over many years, the creative minds of Bartels microEngineering have initiated great amount of technologies and applications and brought many of these to perfection. On this site, you find a selection of former and current projects:


Ho-Pro – 3D

LOGO Europische Union

Either fast or precise – both cannot be achieved in the production of the finest polymer structures with the laser. Or maybe they can? Combining stereolithography and multiphoton polymerization should make it possible: Scientists at the Fraunhofer Institute for Laser Technology ILT are developing a machine for high-precision, cost-effective 3D construction technologies using both methods. On November 1, 2018, Fraunhofer ILT and its project partners Bartels Mikrotechnik GmbH, Miltenyi Biotec and LightFab GmbH launched the project “High Productivity and Detail in Additive Manufacturing through the Combination of UV Polymerization and Multi-Photon Polymerization – HoPro-3D”, which is funded by the European Union and the state of North Rhine-Westphalia.

Innovation targeting the ERDF support


LOGO Europische Union

The aim of the project SeQuLas is the development of a novel process technology for the absorber-free laser welding of thermoplastics. On the basis of a continuously updating temperature field, a segmentation of the seam contour and an adaptation of the irradiation order and parameters should take place during the welding process, and thus a defined energy input should be realized. This will contribute to increasing the flexibility and efficiency of industrial production in North Rhine-Westphalia. Period: 03/2017 – 09/2019

This project is funded by the European Union and the state of North Rhine-Westphalia.

Application range: digital microfluidics – flexible handling of small liquid volumes

Bringing novel technologies into medical applications, the Bartels micro-Engineering division offers development support and product innovation through microtechnology. The direct control of fluid operations offered by digital microfluidics is a key driver for the future development of microfluidic diagnostic systems.



Spraying                                                                                                                                                                            REF spray technology

Application range: medical inhalation, diffusion of fragrances

In the course of these works Bartels microEngineering optimized a spraying method by which various fluids are being atomized almost on a molecular scale without any droplet occurrence. The principle Bartels microEngineering originally utilized for the spraying of active agents and scents can be applied in many further sectors. For example, it can be used to apply extremely fine coatings or to create exact dosings of minimal fluid amounts.



Fluidic Muscles                                                                                                                                                             Ref fluidic muscles

Application range: medical systems, human-machine interacting

Working for a supplier of the automobile industry, Bartels microEngineering has filed a patent application for an adjustment mechanism tilting larger components. For a customer in the sector of personal care, a modified version of this principle has been realized for a microfluidic vibrating element. Further applications have already been conceived and are coming to realization on behalf of our customers.

The mechanism uses the principle of so called “fluidic muscles”. When these “muscles” are being filled with a fluid, they deform in such way that they exert a force on other parts.


Lab-on-a-Chip                                                                                                                                                                Ref lab on a chip

Application range: medical systems, biological analysis, drug detection

Only the size of an object slide, this Lab-on-a-chip combines numerous functional elements to transport, mix, filter, isolate, incubate and analyze tiny samples of liquids. With this complex microfluidic device, several indicators can be tested simultaneously and made interpretable by visually displayed results.

Together with development partners, Bartels microEngineering worked on the project Physiocheck realizing a mobile analysis unit for body fluids.


Microgripper                                                                                                                                                                  Ref microgripper

Application range: medical applications

By order of ErbeElektromedizin GmbH Bartels has developed a microgripper for minimally invasive surgery.

The miniature tongs with an outer diameter of only 1.5 mm have two electrically conductive tips. They serve to exactly fix tissue and cut or obliterate it by use of a high-frequency current.



Application range: microfluidic flow detection, pressure detection, particle detection, component analysis, …

Due to its small dimensions, our micropump can be operated in combination with a sensor, i.e. as integrated module, or implemented as OEM component in a more complex device. Particularly for portable devices – where miniaturization plays an essential role – the low energy consumption gains in importance. Battery operation can be easily realized with the micropumps. Depending on the customer’s demands, electronics can be combined with the system’s electronic or installed into an enlarged pump housing.


Drug dosing

Application range: medical, pharmazeutical and biotechnological applications

Wherever nowadays healthcare services are reqired, dosing the correct amount of active ingredients is a necessity. Having automated solutions in order to dose the correct amount of medicine is increasing in importance, with the target of decreasing pressure on doctors and medical staff. The same goes for the production of such agents, where accurate mixing is required in fully automated processes. Providing solutions for both use cases is part of
Bartel´s microEngineering capabilities.
