Our Micro Valves and Fluidic Systems

Recent scientific advances and innovations are helping to establish microfluidics as a key technology for the future. The precise manipulation of small amounts of fluid is playing an increasingly important role in the fields of medicine, analytics and chemistry.

Flexible system solution for microfluidics

memetis develops and manufactures ultra-compact miniature valves. Innovative actuator technology based on shape memory alloys ensures increased miniaturization of fluidic components and systems and the resulting high portability or packing density.

Today's medical and analytical devices often require dimensions where solenoid valves with solenoid coils reach their technological limits.

Miniature valves tailor-made at the blink of an eye

Microfluidic applications require ever smaller, yet very powerful valves that take up minimal space. This applies not least to portable applications in medical devices that are placed directly on patients or even implanted. Many stationary medical or environmental analytical devices also require high-performance miniature valves with dimensions where solenoid valves with solenoid coils reach their technological limits.

Miniature valves for advanced fluidics

We are convinced that film-based SMA actuators can play out clear technological advantages in numerous applications. These include fluidics, in particular valve technology. The high flexibility in design adaptation as well as ultra-compact dimensions allow us to manufacture high-performance valves with greatly reduced installation space requirements - and always easily adapt them to customer-specific requirements.

In addition to valve technology, the application-specific development and manufacture of fluidic systems and platforms, especially for analytics (e.g. lab-on-chip), are particular strengths of memetis.

Valve technology

memetis bundles many years of research in the field of valve technology and therefore has a broad portfolio of variants and technologies at its disposal in order to be able to meet even challenging requirements. What all our valves have in common is that the SMA actuator used and the continuously optimized layer structure allow great flexibility for customer-specific requirements. Thus, our valves can be adapted extremely quickly to different pressure and flow ranges and different materials (e.g. for biocompatibility) can be taken into account in the design. This modularity allows our valves to be used in numerous applications ranging from bioanalytics (e.g. media-separated, flushable or biocompatible) to production automation (e.g. high flow rates or fast closing).

Among other things, we can develop and manufacture the following valve types at short notice according to your requirements

  • 2/2-way valve (monostable) - Normally open (NO)
  • 2/2-way valve (monostable) - Normally closed (NC)
  • 2/2-way valve (bistable)
  • 3/4-way valve (monostable) - Normally open/ closed (NO/NC)
  • 2/2-way/ Multi-way control valve (continuous)

Fluidic systems

Numerous applications demand high portability of the devices while at the same time taking specific requirements into account. This applies in particular to analytics and diagnostics, where fluidic systems are worn directly on the patient or where analysis chips must be microscopable directly in the system.

We have made it our task to meet these requirements and always supply the appropriate fluidic system. Our competence in the field of microstructure technology enables us to use our own miniature components (e.g. valves) as well as the customer-specific implementation of fluidic logics in highly portable format. A high vertical range of manufacture also enables us to manufacture quickly in-house. Requests for electrical control can also be flexibly taken into account.

PROPERTIES AT A GLANCE

Flexible system solutions for clear differentiation
01 /
CUSTOMIZABLE DESIGN

The layered structure of memetis' miniature valves enables simple and very stable designs, which can reflect market and customer specific requirements. Complex fluidics and multi-channel valves are also part of memetis' performance spectrum.

02 /
Silent operation

Shape memory alloys (SMA) as used for memetis' valve actuators enable silent operation. This enables application fields with increased noise sensitivity.

03 /
BIOCOMPATIBLE & LOW FATIGUE

The materials used by memetis are biocompatible and thus also suitable for use in medical technology or biotechnology. For particularly high requirements, fatigue-free materials with significantly increased operating times (over 10 million switching cycles) can be used.

04 /
COMPETITIVE PRODUCTION

The innovative memetis process and selected materials allow the manufacture of competitive miniature valves. memetis' valves operate efficiently and reliably and thus help to save costs.

Easy integration of active components

Processes normally performed in a laboratory can now be miniaturized on a single chip and performed at the point of care/ point of need to increase analysis and diagnostic efficiency and speed by reducing sample and reagent volumes.

Our valves and components are highly integratable and are the key to enabling the technology developed by our customers. This is especially true in medical technology and analytics, especially in biomedical sample analysis, which usually requires a complex fluidic architecture. At the interface of physics, chemistry, nanotechnology and biotechnology, memetis can revolutionize the way patients are diagnosed, monitored and treated.

Safe human-machine collaboration in mass production
Valve technology

With its pressure sensitive skin for robots and End-of-Arm-Tooling (EOAT) AIRSKIN®, Blue Danube Robotics offers an innovative solution for improved human-machine-collaboration in mass production. memetis supports with its ultra-compact valve technology.

Initial situation

Nowadays robots are an indispensable part of mass production. However, many of the robots used there are secured in cages to protect "human colleagues" - robot systems that guarantee the safety of workers are usually expensive and have not yet widely been used. With the pressure-sensitive AIRSKIN® system, cages and other safety systems are a thing of the past. Existing robots can be retrofitted with the system.

Challenge

The AIRSKIN® system consists of a thin skin filled with air, which can detect the slightest pressure changes (e.g. in the event of a collision) and bring the robot to a standstill. To keep the pressure in the system constant, Blue Danube Robotics requires an ultra-compact, especially flat valve, which places the highest demands on tightness as well as flow. Due to these unusual requirements, an application-specific valve solution is required.

Solution

memetis develops a micro valve which meets the requirements of Blue Danube Robotics: High flow and density in the low pressure range. And all this with the smallest dimensions!

Client comment / Blue Danube Robotics GmbH

"For our product AIRSKIN we need electrically controllable micro valves in the lowest pressure range for the medium air. In addition, we require leakage values that are not common in the industry. After a long unsuccessful search for suitable products, we found memetis to be a company that could offer us a tailor-made solution. By combining problem-solving affinity with series production and very close customer cooperation, memetis turned out to be the proverbial needle in the haystack for complex industrial fluid technology solutions. The memetis valve not only makes our product better and more robust, but also safer."

Application Specific Fluidics for Organ-on-Chip
Fluidic platforms

vasQlab offers a system to replicate organ-specific human tissue in vitro. memetis supports the development and implementation of a customized fluidic platform for the operation of the vasQchip.

Initial situation

vasQlab has set itself the goal of reducing animal experiments within the context of research by means of an innovative organ-on-chip model. This is achieved by replicating organ-specific human tissue on the vasQchip in vitro.

Challenge

The operation of the vasQchip requires a fluidic periphery which is characterized by simple and safe handling as well as stable and error-free operation. Due to different requirements and potential chip designs, an easily adaptable fluidic platform is currently required to meet these needs. However, the availability of such a platform, which can be described as viable from a technological and economic point of view, is currently not guaranteed.

Solution

memetis develops a fluidic platform on the basis of modular components, which accounts for the specific requirements of vasQlab. These can be quickly adapted with limited effort to minimize development cycles and accelerate the testing of the technology.
