ZiuZ builds devices for visual inspection of pouches filled with personalized doses of medication. Strings of pouches are fed through the ZiuZ inspection systems at high speed. Taking the right image, with at the right place is critical for a good analysis. Furthermore these strings of pouches are cut and rolled whereby cutting at the exact position is key.


ZiuZ uses an ultrasonic splice detector to find the seal edges of foil-wrapped (pouch) medication. These sensors work by sending an ultrasonic signal of 400Khz through the material and collecting it again behind the material. Because one thick layer of material dampens the signal less than two half as thin layers, it is possible to distinguish the places where the material has fused together from the places where the material has two layers.

For example, the output amplitude, the processing of the signal and the wavelength of the sound influence this detection.


The assignment consists of building components of an ultrasonic sensor with which it is possible to investigate these separate factors.

Deliverables are:

  • Prototype / Proof of Concept / Proof of Principle.
  • Report with advice.


What is expected of you?

  • Willing to really drill down into a problem.
  • Conceptual thinker but bias for action.
  • Ability to work independently but also in a team.


ZiuZ has a standard internship / graduation allowance of € 275 per month and a maximum of € 100 travel allowance if applicable.
