Our Service

Tests & Characterization

Electrical and Electrochemical Tests

  • Impedance spectroscopy
    Characterization of the recording performance of the electrode.
  • Pulse testing
    Characterization of the stimulation performance of the electrode.
  • Corrosion testing inclusive SEM inspection
    Evaluating the corrosion resistance of a particular electrode design for a given stimulation paradigm.
  • Dielectric strength

Mechanical Tests

  • Reliability testing
    Cyclic bending and pull tests to obtain typical lifetime characteristics of electrodes or interconnections – if desired under particular environmental conditions, such as HALT (Highly Accelerated Life Tests).
  • Tensile or shear tests
  • Bending and fl exing tests (cyclic or ultimate strength)
  • Layer pull strength (adhesion)
  • Hardness testing (micro IRHD)

System Integration Tests

  • Functionality testing
  • Hermeticity qualification (helium gross and fi ne leak testing)
  • Long-term functionality testing
    If desired also under accelerated aging conditions.


With our patented °AirRay electrode technology we have overcome current limitations of electrodes.

Based on our laser-aided manufacturing process we can design and manufacture electrodes according to your actual requirements – in any geometrical shape, with hundreds of contacts, and for numerous applications.
