COMSOL Simulation for Capacitive Force Sensor

I'm looking for a skilled COMSOL simulation expert to help develop and simulate a capacitive force sensor intended for medical devices. The most critical performance metric for this sensor is its sensitivity.

Key requirements:
- Extensive experience with COMSOL Multiphysics
- Prior work with capacitive force sensors
- Understanding of medical device specifications
- Ability to optimize for sensitivity

The ideal freelancer for this project would be someone who can not only perform simulations but also provide insights for improving the sensor's sensitivity for medical applications.
