The Shimmer in its enclosure. Baseboard includes Bluetooth and 802.15.4 radios. The Shimmer baseboard also contains a MicroSD card socket to incorporate extra memory resources, with up to 2Gbyte currently available. This allows the additional storage of data while the Shimmer is not streaming and ensures no loss of data while mobile or out of network range. The Shimmer base board also includes a tri-axial accelerometer with selectable range as standard.

Left to right - the Shimmer baseboard, ECG daughter card and Gyro daughter card. The ECG board pictured in the center of the image above is used to capture ECG data. The frequency response is .05Hz - 150 Hz with an ECG amplifier gain of 175. The Gyro board seen on the right above is an internal expansion board designed for motion capture applications. The design uses a pair of dual-axis gyroscopes. The flex segment wraps around the Shimmer module to properly orient the sensors for tri-axial measurement.

A USB reader is used for programming Shimmer. This also can be used as a single unit charging dock and is connected via USB cable to any PC or laptop.

The multi charger is a battery charger cradle that can charge 6 Shimmers simultaneously. This is powered from the mains and is shipped with a power supply and region specific plug.

The ECG top enclosure. This is swapped out with the Shimmer top and connects with the Shimmer base enclosure to form the ECG Shimmer.

The analog expansion module enables two analog signals to be plugged into Shimmer.

The AnEx board plugged into the Shimmer module is seen above. Existing physiological sensor systems that have been tested on this include EOG, EEG, EMG and GSR.

The Shimmer SDK as shown above includes: 2 Shimmer baseboards with enclosures, ECG daughter card with enclosure, Gyro board, AnEx board, USB reader/programmer with USB lead, 6 gang multi charger with PS and region specific plug, one 2 GB Micro SD card with adapter, a bootable Shimmer Live DVD and the Shimmer manual.
