Capacitive sensor, theory and design.

This is a great explanation! I'd be very interested in learning about how you visualized the electric field. Is the Matlab code you used available somewhere?

[@RandyRobert36]

You have done a fantastic job! Thank you so much for making these....and please disregard my previous questions posted on your other video. This video answered my questions very well.

Best video that explains of capacitive touch ,

[@Bowsh00ter]

Really nice video! Would you share your simulation software?

[@pjggregory]

Could you please tell me what tools/software you used to measure the capacitance as a function of distance. Thanks

The capacitance is computed by a MoM code I wrote on Matlab. Every step when the finger moves closer to the electrodes, MoM Matrix is re-constructed and solved for the charge distribution. From the charge distribution, the capacitance is then obtained.

Bro...can you mention that which capacitive sensing module are you using?

[@SiliconSoup]

The sensing ic and demo board I used is from Azoteq. The website is www.azoteq.com

how to download this video...?

RealPlayer is a KZbin downloader.
