Hello Thomas,
We are using Nexus 10 (http://www.mindmedia.nl/english/nexus10.php)
and Nexus 4 (http://www.mindmedia.nl/english/nexus4.php) for bio-
signal acquisition in our project, currently we are implementing the
PD [audio-visual engine] part of the system, we trace the signals by
integrating a Python script to Mindmedia's Biotrace+ (http://
www.mindmedia.nl/english/biotrace.php) and we stream data through OSC.
Skin conductance sensor with the above combination, is like a hand
touch sensor available for measuring pulse. On the other hand piezo
contact mic can be used as a sensor to receive pulse, but I guess it
should be tested to see how much reliable output can be received
though a contact mic.

Hi all, does anyone have experience with measuring pulse using just hand touch sensors? Which kind of sensors are feasible, is there any special signal conditioning necessary?
many thanks, gr~~~
