Key Points
Trigno™ IM
1
What types of hardware are in the
Trigno™ Inertial Measurement
(IM) sensors?
The Trigno™ IM sensor
contains Delsys’ patented
parallel-bar EMG hardware,
accelerometer, gyroscope
and magnetometer.
2
How many signals does a single
Trigno™ IM sensor record?
Each Trigno™ IM sensor
records a total of 10 signals.
These consist of EMG, 3D
accelerometry, 3D rotational velocity and 3D orientation.
3
The Trigno™ Inertial Measurement (IM) Sensor incorporates 9 DOF Inertial Measurement
scheme into the DELSYS wireless EMG sensor, providing 10 channels of high-resolution,
16-bit, real-time data to study:
EMG
Acceleration
Rotation
Direction
Our
patented
parallel-bar approach
uses
two EMG inputs
with proprietary
stabilizing references, creating
a high quality
EMG signal while
reducing noise
sources.
Triaxial acceleration is measured
using an accelerometer, which
records at 148
samples per second and up to
±16g with 3 additional selectable
ranges.
Triaxial rotational
Triaxial
magnetic orientation
is measured using a magnetometer, which
records at 74
samples per second in the ±1 mT
range.
velocity is measured using a gyroscope, which
records at 148
samples per second and up to
±2000
degrees
per second with
3 additional selectable ranges.
4
How do I collect and process the
IM data?
Raw signals may be collected digitally using
EMGworks®. In addition, we
also provide the user with
a digital software development kit (SDK), which can
be used to stream the data
directly into 3rd party applications (LabView, MATLAB,
C/C++ based programs,
etc.).
Are the Trigno™ IM sensors
compatible with existing Trigno™
Base Stations?
Yes, the Trigno™ IM sensors are compatible with all
existing base stations.
