Applications

The products of Desaar can serve in a wide variety of applications. Below you will find some selected applications, which prove the feasibility of the technology.

application of dielectric elastomers

01

Research activities

In-plane movement

Strip-in-plane (SIP) actuators can be used for positioning, pumps (or drives) for valves and haptic feedback, if a very flat overall size and in-plane movement is needed.

  • Very flat designs possible (<5mm)
  • In-plane movement

Out-of-plane movement

The out-of-plane actuator can be used for similar applications as the in-plane actuator. However, it is a very compact design alternative.

  • Very compact design
  • Flat design for out-of-plane movement

Valve

Desaar’s actuator can also serve as very efficient drives for valves with and with-out proportional flow control.

  • Proportional flow control without additional sensors
  • High energy efficiency
  • No heat generation

Loudspeaker

The bandwidth of Desaar’s actuator ranges up to the kilohertz range. This allows for use as light-weight speakers.

  • Light-weight
  • Highly dynamic
  • No magnets or magnetic fields

Haptic display

Adding an actuator to a commercially available touchscreen gives it a third dimension sensation. It allows simulating three dimensional buttons or surfaces by maintaining a compact overall size.

  • High integration density
  • Light-weight system

High Force applications

This example shows the potential scalability of dielectric elastomer actuator systems developed with Desaar’s know-how. A mass of 10 kg (22 lbs) can be lifted 3mm (0.1 inch).

  • Scalability
  • Adaptability
  • High integration density

Contactor

A circular-out-of-plane DEA is used to move the contactor. The technology could even fulfil the high speed requirements (>400 mm/S).

  • Fast switching
  • High energy efficiency
  • Position feedback

Pump

The actuators of Desaar are able to drive a pump, too. Our technology allows to run the pump at a constant frequency and control the flowrate with the voltage applied.

  • Silent operation
  • Flow-rate proportional to applied Voltage
  • Design freedom (very flat of compact)
