SHIMMER is a small wireless sensor platform designed to support wearable applications. It provides an extremely extensible platform for real-time kinematic motion and physiological sensing. It features a large storage capacity and low-power standards based wireless communication technologies which facilitate wearable or wireless sensing in both connected and disconnected modes.

SHIMMER provides an extremely compact extensible platform for long-term wearable or wireless sensing using proven system building blocks. The design is realized using conventional design and assembly technology to ensure repeatability and economy. SHIMMER will help to create an ecosystem of health-related technologies that provide a highly mobile capability which is tightly integrated with supporting infrastructure.

Platform Features

  • Compact Form Factor, Light & Wearable (Weight: 15 Grams, Volume: 50mm x 25mm x 12.5mm)
  • Support for Bluetooth and 802.15.4 wireless communications (WML-C46A, CC2420)
  • Offline Data Capture - Micro SD Card Storage - 2 Gigabytes
  • Open Platform, driven by TinyOS
  • Internal and external connectors for expansion
  • Integrated TCP/IP stack for 802.15.4
  • Integrated 3-axis MEMs accelerometer with selectable range
  • Integrated Li-ion battery mgmt.

Available as add-on extension boards and accessories:

  • Kinematics sensing (3 axis Gyroscope)
  • Advanced Kinematics sensing (3 axis Gyroscope + 3 axis magnetic sensing)
  • 3 Lead Micro-power electrocardiograph (ECG)
SHIMMER with ECG sensor board.
  • Breakout board to thru-holes for rapid prototyping
  • USB programming/charging dock
  • 6-SHIMMER Charger

Software

SHIMMER platform support is found in TinyOS 1.x in the contrib/handhelds directory. A sample SHIMMER application for data collection can be found in the TinyOS 1.x contrib/harvard/spaulding directory.

The SHIMMER platform is being utilized for a variety of applications. These include:

  • Limb motion analysis of Parkinson's Disease and stroke patients - see CodeBlue for details
  • Gait Analysis
  • Sleep Studies
  • Cognitive Awareness
  • Activities of Daily Living Studies
  • Vital Signs Monitoring
  • Chronic Disease Management
