Sensors Simulation

This note uses EMWorks Electric Conduction to simulate a single silicon solar cell, computing voltage drop, electric field and current density between aluminum front and back electrodes.

This application note studies an inductive proximity sensor that detects a conductive target by monitoring changes in PCB coil inductance. An AC magnetic analysis at 1 MHz is used to compute coil inductance, resistance, magnetic flux density, field intensity, and eddy currents for different target positions. Results show a measurable inductance drop as the metal target moves above the coil, along with reduced flux near the sensor due to induced eddy currents. These quantities help designers size the sensing circuitry and set thresholds for reliable position detection.

Capacitive touch panels rely on controlled electric fields and precise inter-electrode capacitances. Using the Electrostatic module, you can model multi-electrode touch panels, apply realistic boundary conditions, and extract the full capacitance matrix. Field and potential plots help validate designs and tune sensor geometry for robust touch detection.
