Shimmer Wireless Sensor Platform

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

Platform Features

• Compact Form Factor, Light & Wearable (Weight: 15 Grams, Volume: 50mm x 25mm x 12.5mm)
• Wireless communications via Bluetooth® and 802.15.4 (WML-C46A, CC2420)
• Offline Data Capture – Micro SD Card Storage – 2 Gigabytes
• SD data bypass 8MHz MSP430 CPU (10Kbyte RAM, 48Kbyte Flash, 8 Channels of 12 bit A/D)
• Open Platform, driven by TinyOS
• Internal and external connectors for expansion
• Includes simple serial command interface for Bluetooth®
• Integrated TCP/IP stack for 802.15.4
• Integrated 3-axis MEMs accelerometer with selectable range
• Integrated tilt / vibration sensor
• Integrated Li-ion battery mgmt.
• Supported by BioMOBIUS™ graphical software platform

Available as add-on extension boards and accessories

• Kinematics sensing – Designed for motion capture applications. The design uses a pair of dual-axis gyroscopes.
• 3 Lead Micro-power electrocardiograph (ECG) – Utilised for the capturing of ECG data
• 2 Lead Micro-power electromyograph (EMG) – Utilised for evaluating and recording the activation signal of muscles
• Passive Infra Red -
• USB reader and programming dock – for programming and applications where wired serial communication are desirable. Also acts as a single Shimmer charger
• Shimmer Charger dock – battery charger cradle that can charge 6 Shimmers simultaneously
• Analog Breakout board to thru-holes for rapid prototyping – enables multiple analog signals to be plugged into Shimmer.
