Handwave Skin Conductance Sensor
= HandWave is a small, wireless, networked skin conductance sensor for affective computing applications.
"It is used to detect informationrelated to emotional, cognitive, and physical arousal of mobile users. The HandWave collects Electrodermal Activity (EDA) data by measuring skin conductance over a pair of electrodes. The EDA data signal is used to infer the excitement level of the subject. The injection-molded housing is affixed to the wrist of the subject, and the electrodes are positioned on the fingers and/or palm. "
From MIT's media lab page:
"Q: How can I build a Handwave skin conductance sensor?
"A: The primary work involved in constructing a Handwave device is in constructing a printed circuit board (PCB). A set of design files for the Handwave device may be downloaded and unzipped. This contains OrCad design files, a bill of materials, schematic, Gerber files, firmware source code, sample drivers, and design files for a programming jib. These files are most useful to those who are experienced computer or electrical engineers and are offered without any support or warranty. Further information can be found in the publications we wrote: The HandWave Bluetooth Skin Conductance Sensor, HandWave: Design and Manufacture of a Wearable Wireless Skin Conductance Sensor and Housing and The HandWave User's Guide.
