E&T webinar - Modelling Capacitive Sensors in COMSOL®

CPD 1 hour logo

This activity can contribute towards your Continuing Professional Development (CPD) as part of the IET's CPD monitoring scheme

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.

Register for this webinar to learn about:

  • FEM and BEM methods for capacitive modelling with COMSOL Multiphysics®
  • Multi-scale simulation using equivalent circuit models
  • Combining resistance and capacitance predictions under AC conditions
  • Exploiting superposition and reciprocity to get sophisticated solutions from simple numerical models
