This white paper looks at a number of capacitive sensing applications to understand how they operate and the benefits they offer over alternative solutions. It then goes on to consider how concerns regarding energy consumption can be mitigated using a microcontroller that can remain in an ultra-low power, deep-sleep mode while still being able to detect and respond to sensor inputs quickly and reliably.
I have a very unique application for capacitive sensing that will open a completely new consumer market. It requires high sensitivity, detecting just a few pF change, and logging that change over time.
Can your method achieve the required sensitivity? It is not practical to increase the size of the sensor plates.
If so, can you point me to an evaluation board?
