Capacitive sensors can be challenging to simulate because of their geometry. This webinar will demonstrate computationally efficient ways to simulate capacitive sensors in the COMSOL® software. Register to watch this live free webinar with Q&A session on 26th May 2022.
A sensor electrode might be 1 millimetre in size, but the electronics ground plane could couple to objects 100 millimetres in size. There can also be extreme aspect ratios, e.g. a sensor with submillimetre gaps between printed circuit board (PCB) layers that extend for 10s of millimetres.
If a straightforward finite element method approach is taken for a 3D model, this can result in a large model that is slow to solve. Furthermore, the geometry is likely to have at least one moving part, and running the model over a range of positions can take an inordinate amount of time.
