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).
This information can be used to monitor in real time the state of a patient or to get sensitive data in order to be subsequently analysed for medical diagnosis. Biometric information gathered can be wirelessly sent using any of the 6 connectivity options available: Wi-Fi, 3G, GPRS, Bluetooth, 802.15.4 and ZigBee depending on the application.
If real time image diagnosis is needed a camera can be attached to the 3G module in order to send photos and videos of the patient to a medical diagnosis center.
Data can be sent to the Cloud in order to perform permanent storage or visualized in real time by sending the data directly to a laptop or Smartphone. iPhone and Android applications have been designed in order to easily see the patient's information.
- What does it mean to count with an open medical monitoring platform?
Cooking Hacks wants to give Community the necessary tools in order to develop new e-Health applications and products. We want Arduino and Raspberry Pi Community to use this platform as a quick proof of concept and the basis of a new era of open source medical products.
- How do I ensure the privacy of the biometric data sent?
Privacy is one of the key points in this kind of applications. For this reason the platform includes several security levels:
- In the communication link layer: AES 128 for 802.14.5 / ZigBee and WPA2 for Wifi.
- In the application layer: by using the HTTPS (secure) protocol we ensure a point to point security tunnel between each sensor node and the web server (this is the same method as used in the bank transfers).
