Informed Consent Statement
Shimmer is an open flexible platform intended for qualified personal conducting research in wearable sensor
applications. Consequently, although great care was taken in the design of this device, there is some inherent
risk both with the design and manufacturing that you assume when the device is in close proximity to your
body or the body of your test subjects. Depending on local regulations, Shimmer may not fully comply with
commercial product testing standards. Shimmer as sold lacks medical certifications (e.g. ANSI/AAMI/IEC).
Shimmer devices should never be used for diagnostic purposes without full consideration of operator and
subject risk. The following list describes some of the subject risks:
There is a risk of electrical shock due to manufacturing defects or improper use (see usage guidelines
and warnings).
There is also a risk of sustaining a burn due to a catastrophic failure of the device which could result
from overheating of components.
There is a risk of radio interference with the operation of other electronic devices and we make no
claims to the consequences of this.
There is a risk of some minor skin irritation from electrode pads over prolonged periods of time which
may cause discomfort.
The device is not designed with proper safeguards for defibrillation. As such, electrodes must be
removed before defibrillation is attempted.
Data privacy limitations: It should be understood from the outset and you should communicate to test subjects
that the physiological data that is streamed, stored, and analyzed through use of the device is not anonymized
or privacy-protected in any way and you should take appropriate precautions in the protection and handling of
such data in your research activities. Shimmer itself may buffer raw physiological data unencrypted on the
integrated flash memory device. RF data streaming from the Shimmer may not be encrypted and could be
intercepted by others. RF data downstream from an aggregation device, such as a cell phone may not be
encrypted and is likewise susceptible to access.
Physiological data generated through use of Shimmer may indicate conditions that your test subject was
previously unaware of prior to participation in research using the device.
There may be a risk of exposure to minute amounts of chemicals from the manufacturing process or the
components themselves (such as latex, lead etc.).
There may be an increased risk of physical injury by the physical presence of the device on a test subject’s
body and you fully assume this responsibility.
Realtime Technologies Ltd is not liable for damage or loss of data when using the Shimmer platform.
Some Shimmer peripherals rely on 3rd party driver support. Whilst Realtime/Shimmer Research have tested
features using a typical system, in some cases the end user will need to contact the peripheral vendor for
resolution of installation, compatibility or operational issues.
By your use of Shimmer you acknowledge these and other risks inherent in the use of an experimental device
and you assume full responsibility for testing this device with human subjects.
This device cannot be marketed or put into service within the EU until it has been made to comply with the
Medical Devices Directive 93/42/EEC. In the United States, Shimmer is an investigational device, limited by US
law to investigational uses.

1. Introduction
Shimmer is a small wireless sensor platform well suited for wearable applications. The integrated
kinematic sensors, large storage and low-power standards based communication capabilities enable
emerging applications in motion capture, long-term data acquisition and real-time monitoring.
Shimmer3, the latest revision of the Shimmer platform includes improvements to the original design
based on years of field trials and deployments. We have made improvements in wearability while
expanding capabilities with a flexible kinematic sensor array, more powerful CPU and improved user
interface. The terms ‘Shimmer’and ‘Shimmer3’are used interchangeably in this manual, to refer to
the Shimmer3 device. Much of the information applies generically to Shimmer Products.
If you are new to the Shimmer platform, there is Quickstart information in Section 2, whilst Section 3
gives a high level overview of the Shimmer platform. Section 2(Quickstart) is essential reading,
Section 3(Shimmer Platform Overview) is recommended reading and the remaining sections are best
browsed based on personal interest and development goals. For details on legacy devices please
refer to Shimmer Clock Drift
Like many embedded devices, the clock on the Shimmer device is prone to drift. Laboratory
experiments have indicated that Shimmer-to-Shimmer clock drift is variable and can be up to 12
µs/s. To equate this to longer recording periods 12µsec/sec is equivalent to 0.72 ms/min, 43
ms/hour and 1.04 s/day.

2. Quickstart
The Support > Getting Started section of the Shimmer website contains step-by-step instructions for
new Shimmer users to help with quickly going from delivery of hardware to streaming data over
Bluetooth to a Windows PC or an Android device. It is highly recommended for new customers to
refer to those instructions.
This Quickstart guide is aimed at those who do not have access to the online instructions and its
purpose is to allow those users to swiftly get up and running with their Shimmer sensing platform on
both a Windows OS and Linux OS. For a more in depth understanding of the Shimmer platform
please refer to the later sections of this User Manual.
Shimmer units are shipped pre-programmed with the LogAndStream firmware program which
allows for Shimmer configuration and data capture over Bluetooth as well as capturing data onto the
SD card of the Shimmer. This Quickstart guide assumes the device has been programmed with
LogAndStream v0.8.0 or later.
2.1. Powering On/Off the Shimmer
Use the slide switch to turn the Shimmer On/Off, as shown in Figure 2-1. Some applications may use
the user push-button to switch between suspend and active modes; details of this functionality can
be found in the appropriate application manual.
Figure 2-1 Shimmer3 in enclosure
2.2. LogAndStream LED Indication
There are two LED locations on the Shimmer3, as shown in Figure 2-1; location A has three LEDs,
coloured red, yellow and green, whilst location B has two LEDs, coloured blue and green. These LEDs
are used to indicate the state of the device, according to the firmware that is programmed on it.
Figure 2-2 and Figure 2-3 provide a summarised translation of LED behaviour when LogAndStream is
running on the Shimmer (for a full LogAndStream LED translation table refer to Section 5.1.1). The
relative size of the LED symbols in the figures denotes how long the LED of the relevant colour is on
or off for, in each case.

2.3. Charging the Shimmer
A Shimmer unit may be charged using a Shimmer Dock, Multi Charger, a Shimmer charging cable or a
Consensys Base. This section is limited to the description of the Shimmer Dock (referred to as "the
Dock" in the following) for charging purposes only. For a full description of the Dock functionality
and charging with the Shimmer Multi Charger please refer to the Shimmer3 Platform Overview
section of this document or the individual User Guides for these items.
Connect the Dock to a powered USB socket.
Warning: If you connect the Dock to a PC, do not allow Windows to install the driver automatically,
as some versions of Windows (typically old than Windows 10) will not install the correct driver1.
Driver installation is not required for charging purposes. For further details on driver installation
please refer to the full description of the Shimmer Dock in the Shimmer3 Platform Overview section.
If using a single Shimmer Dock, insert the Shimmer3 unit into the dock with the Bluetooth ID label
facing away from the USB cable.
Warning: Forcing the connector may cause permanent damage to your Shimmer. If you have
difficulty inserting the unit into the dock, check that you have the correct orientation.
A detailed explanation of the charging process is outlined in the Section 3.2.3 of this document.
If the Shimmer is powered on, when a charging source is available, the Shimmer will indicate charge
status using the Battery status LEDs on the device; while the Shimmer is charging, the yellow LED will
be on and once the battery is full, a green LED will be on.
2.4. Pairing a Shimmer
In order to capture data from a Shimmer sensor using a Bluetooth connection, the Bluetooth
connection must first be set up in a process called Pairing. Two pairing procedures are outlined
below: one for a Windows operating system and another for a Linux operating system. You should
follow the procedure which applies to the OS you are using.
Note: The host side machine must have a plug-in or built-in Bluetooth radio installed and activated
to continue.
2.4.1. Bluetooth Pairing in Windows
To pair the Shimmer (or any Bluetooth device) with a Windows OS, ensure that the unit is powered
on and follow the steps below.

2.4.2. Bluetooth Pairing in Linux
The operation of pairing a Shimmer device in Linux may vary from distribution to distribution. The
following procedure has been tested in Ubuntu 10.04, Slackware 13 and OpenSuse 11.3.
All the commands given here should be entered from the command line (in a terminal window).
Bluetooth Radio
The BlueZ Bluetooth libraries and tools need to be installed. See http://www.bluez.org for details.
Ensure the Bluetooth radio is available by running the hciconfig command.

Pair to a Shimmer device
To use the Shimmer, for example, with Bluetooth radio ID “RN42-2418”, it must be bound to an
rfcomm device. The rfcomm bind <n> <MAC_ADDRESS> command achieves this. The <n> parameter
gives the rfcomm device number, which must be different for each Shimmer paired, and the
<MAC_ADDRESS> parameter is the Shimmers MAC address which can be obtained from the hcitool
scan output above. This command normally needs root privileges, so “sudo” is used.
tiny2@ShimmerLive:~/Desktop$ sudo rfcomm bind 0 00:06:66:42:24:18
[sudo] password for tiny2:
Verify a Successful Bluetooth Pairing
Running the rfcomm command with no arguments shows which Shimmer is bound to which rfcomm
device, along with the current connection status.
