In the many years we have provided development services, the creative minds of Bartels microEngineering have initiated or brought to perfection a great number of technologies and applications. On this site, you find a selection of former and current projects:

  • Electrowetting Displays Open or Close

    For our customer ADT (Advanced Display Technologies) Bartels microEngineering developed power saving displays based on the electrowetting principle.

    Ref Electrowetting

    Colored droplets are being moved by an electric field and brought into position as the display's pixels. Once they reached the programmed position, no more energy is required to keep them in place.

    That opens a promising future perspective from indicators to large-scale applications as for example billboards. Read more about "Displays & Indicators: Droplets and Pixels" in an article from Richard Babyak, Appliance Design magazine.

    With bistableelectrowetting binary states of single droplets can be controlled. These digital microfluidics exhibit a great potential in other sectors as well.

    Application Note: Digital Microfludics for micro liquid handling

    Bringing novel technologies into medical applications, the micro-Engineering division from Bartels Mikrotechnik 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.

  • Implantable Micropump Open or Close

    On behalf of an internationally active supplier of medical devices Bartels microEngineering is currently designing an implantable micropump.

    By inflating a device with a liquid, this pump is going to adjust a non-medicamentous device for the manipulation of body functions.

    In combination with an implanted reservoir the pump will supersede port catheters for manual adjustments









  • Spraying Open or Close

    In the field of spray generation Bartels microEngineering has accomplished numerous development jobs, among those several.

    REF spray technology

    for an international market leader in the fragrances industry.

    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 Open or Close

    Working for a supplier of the automobile industry, Bartels microEngineering has filed a patent application for an adjustment mechanism tilting larger components

    Ref fluidic muscles


    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.
    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 comming to realization on behalf of our customers.






  • On-chip synthesis Open or Close

    Task of this development project was a microfluidic chip system for mobile synthesis of chemicals.

    Ref on chip synthesis

    Based on a reaction scheme and general chip layout combined with a material choice the following topics as fluidic design, low cost actuation mechanisms, electrical structures / interfaces, assembly and fabrication technologies were addressed. Together with external partners the concept was proven by fabrication of a pilot lot by injection molding. After successful assembly and test of the chips the proven design is being transferred into mass fabrication.

    The application of such systems can for example be found in the radio-pharmaceutical industry driven by the needs for cost effective and faster preparation of unit patient doses, the need for lighter transportation systems and hospital’s needs for reduced exposure.



  • Alchemist Open or Close

    For formulation processes of high complexity mixing, as to be found in chemical and

    Ref dosing

    pharmaceutical industries, Bartels microEngineering has developed the compact and fully automated dosing robot Alchemist. Up to 211 different liquids can be stored in the Alchemist's glass syringe reservoirs and dosed steplessly in amounts between 500 µg and 10 g, creating mixtures of high accuracy.







  • Micromixer Open or Close

    Conception, simulation and prototyping of a micromixer have been accomplished by Bartels microEnginerring for the European Synchrotron Radiation Facility (ESRF).

    Ref micro mixer

    The mixer includes a replacable fluid cell with channels of only 100 µm x 100 µm width, in which minimal amounts of two liquids are being joined in a laminar flow. The central challenge was to create a parallel stream of aggressive fluids on small space and provide a long section for mixture by diffusion. This was achieved using only highly inert materials like PI and PEEK.






  • Lab-on-a-Chip Open or Close

    Together with development partners, Bartels microEngineering worked on the project

    Ref lab on a chip

    Physiocheck realizing a mobile analysis unit for body fluids. 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.






  • Microgripper Open or Close

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

    Ref microgripper

    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.
