Shimmer Small Wireless Sensor Platform

Interesting new sensing platform which looks great for bio-sensing

Shimmer Small Wireless Sensor Platform Designed to Support Wearable Applications
Wireless Sensors have progressed in recent years due to the development of micro electromechanical MEM technology. However, traditional constraints such as size, weight, reliable wireless communication and power consumption are issues that wireless sensors must contend with. Shimmer provides and extensible platform that allows you to overcome traditional hardware and software constraints through the following features:

Very low power consumption
Soft power switching
Small form factor: 50mm x 25mm x 12.5mm
Light weight: 15 grams
Readily connects via Bluetooth or 802.15.4 radio
