[PD] pulse measurement using touch sensors

[Koray Tahiroglu]

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.
