AmmSensor™ is a revolutionary new real-time wireless 3D sensor that is Bluetooth enabled. This 3D (6DOF) inertial measurement unit (IMU) samples at 250Hz and provides motion data by employing three miniature tri-axial MEMS chips to capture acceleration, the earth’s magnetic vector and angular velocity. AmmSensor™ combined with AmmGraph3D™ software will capture and display both the raw sensor signals:
- acceleration (Ax, Ay, Az),
- magnetic field (Mx, My, Mz),
- gyroscope (Gx, Gy, Gz)
And the orientation unit vectors:
- X-Axis (Xx, Xy, Xz)
- Y-Axis (Yx, Yy, Yz)
- Z-Axis (Zx, Zy, Zz)
An advanced Kalman filter is used in this process to obtain the most accurate orientation results possible.
The AmmSensor™ has a superior technical performance specification: (www.AmmSensor.com)
-
Fast sampling rate of 250Hz.
-
Rotational velocity switchable in two ranges; up to 400 degrees/sec for slower motions and up
to 2,000 degrees/sec for faster motions such as a golf swing or throwing.
-
Accelerations are also switchable in two ranges ±4gs and ±12gs.
-
It’s small: 2.75” x 1.7” x 0.7” / 68 x 43 x 18mm, light: 1.5 oz / 42g and inexpensive!
-
A sensor unit is self-contained with an internal rechargeable battery, which gives it up to eight hours of life.
-
It communicates and transmits 3D motion data to a laptop via Bluetooth technology; this also means you
could even write your own software for a Windows Mobile, iPhone or Droid smart phone to provide the
ultimate in portability.

AmmSensor™ is the most versatile, lowest cost Bluetooth enabled IMU/sensor in the world today! It can measure human motion, machine motion or any motion! AmmSensor™ has been designed for high speed sports motion (2000d/s and 12g) but can easily be switched to measure slower motion for rehabilitation applications (400d/s and -4g). The attractive slim line package can easily be worn on the wrist, leg, around the waist or on any part of the body!
AmmSensor™ can be used in many life science areas and in a myriad of industrial applications: • Biomechanics Research Motor Control • Rehabilitation • Biomedical Engineering • Sports • Physical Therapy • Psychology • Neurology • Educational Demonstrations, e.g. Physics Classes. Also in: • Aging • Slip and Fall • Gait • VR • Forensic Medicine • Augmented Reality • 3D Simulation Training • Gaming Industry • Ergonomics • Aerospace • Automotive • Marine • Military.
AmmSensor’s output can be changed between binary and ASCII by the user. Binary mode provides 250 complete samples per second, whereas ASCII output is 125 samples per second, and is intended for ease-of-use with any terminal program that can receive 115 KBaud data. The software also computers unit vectors of the sensor’s orientation. From these unit vectors many different 3D angle sets can be computed; such as Euler angles, Cardan Angles etc. These data are transmitted from the AmmSensor™ in real-time to a Windows compatible laptop. AmmGrraph3D™ allows for capture to a comma delimited file, which opens MS Excel to display and save the current data.
The real-time aspect of the AmmSensor™ allows it to be used as a biofeedback training tool (e.g. AmmTrainer3D™ – see www.amm3d.com of more details). Motion biofeedback or motion data logging applications allow AmmSensor™ to be attached to a segment of the body and be used in sports, rehabilitation and other fields.

Place one AmmSensor™ on the tibia
and one AmmSensor on the foot to
measure dorsiflexion and plantarflexion.

Write your own programs in most languages: VB, C#, C, Matlab and Labview using a simple software demonstration program in VB that we provide. Since the AmmSensor™ uses Bluetooth you could even develop programs of your own for Windows Mobile, iPhone or Droid smart phones. This allows for ultimate portability.
The AmmSensor™ plus AmmGraph3D™ allows the user to graph all nine outputs of the AmmSensor™ including X, Y and Z for the magnetometer, accelerometer and gyro. It also allows capture to a comma delimited file and directly opens Excel with the current data.

AmmGraph3D™
Displaying the AmmGraph3D™ Data
After the AmmSensor™ is turned on, the user chooses the serial port number and clicks ‘Open Port’ and ‘Read Data’. Now real-time data will be streaming on the screen and the values will be rapidly changing. The magnetometer, accelerometer or gyroscope can be chosen to graph by clicking the appropriate button. The user will see the three graphs changing when the AmmSensor™ is moved.
Once connected the software displays the data values from all nine sensor channels in real-time. The main screen is shown to the right.

Graphing All Channels
To graph all the 9 channels of data the user clicks Start Capture, moves the sensor then clicks Stop Capture (the same button). Open Graphs now shows the following screen:
|
|
These data are automatically saved to a comma delimited data file which can be read into Excel by clicking the Open Excel button.
