Miniaturisation

Miniaturisation of the handheld sensors makes it possible to perform measurements at any desired location. For example, a patient can monitor their own illness or a citizen can monitor the air quality of their own living environment. But small sensors make the difference in the factory as well: they contribute to the qualitative and efficient production of components, such as food products and medicines or improved diagnostics.

First of all, we can investigate the feasibility of miniaturization:

Feasibility

Miniaturisation of a measuring instrument is often at the expense of accuracy and repeatability. Of course, the measuring results must remain of use for the process. We make models with which we can map out the effect of miniaturisation, so that you can weigh up the pros and cons

The Citizen Science Living Lab also offers access to various micro-manufacturing techniques, such as lithography and silicon micromachining.

Showcase

In order to speed up the concentration determination in their raw materials, a customer wanted to use miniature handheld NIR (Near Infra-Red) sensors instead of the benchtop equipment in their laboratory. We investigated what the possible effect could be on the accuracy and correctness of the concentration determination. We used reference measurements with the accurate benchtop equipment and available specifications of the miniature NIR sensor. Later tests with the miniature NIR sensor showed that the predictions corresponded with the results of the tests.
