Fantastic new product from Cooking Hacks. Quite pricey at 290 euros, but so many practical applications!

The e-Health Sensor Shield allows Arduino and Raspberry Pi users to perform biometric and medical applications where body monitoring is needed by using 9 different sensors: pulse, oxygen in blood (SPO2), airflow (breathing), body temperature, electrocardiogram (ECG), glucometer, galvanic skin response (GSR – sweating), blood pressure (sphygmomanometer) and patient position (accelerometer).
