Hey guys, didn't really know where to put this one!

What i'm wondering is how the humans body capacitance changes in different conditions. In many places, i've seen the human body capacitance quoted at around 100pF when floating, how does this change when a human has say shoes on or is on a highly insulative surface?

How is this capacitance calculated?

Any information on the subject is greatly appreciated.
 

Thank you very much for the reply, they're brilliant articles!

One thing I am wondering about simulating human body capacitance is whether I can literally connect a capacitor in series with a 1.5k resistor direct to ground, so simulate a human touching that point?
 

Thats very true! Though I do generally like to simulate a circuit first before sending off to get PCB's made, I could always breadboard it though. I'm still thinking of ways to use capacitive touch though.
