The complying with provides an example of sample Shimmer Data collected internally on both Shimmer3 motion (IMU) and also biophsical (ECG,EMG, GSR, Respiration, Optical Pulse PPG) units. MATLAB was offered to plot the raw data collected.

You are watching: Which of the following provides an example of data?

Wide variety Accelerometer

The Shimmer3 IMU unit was initially placed ~ above a desk and then lifted off the desk and also rotated about each that its three axes. In between each axis rotation, the Shimmer to be placed flat on a workdesk to demonstrate a stationary duration of the device.

The kinematic data was passed through the 9DoF-to-IMU algorithm, which deserve to be discovered in our Consensys software application. This algorithm produced 9DoF Quaternion data indigenous the calibrated Low-Noise Accelerometer, Gyroscope and Magnetometer data.

Gyroscope

The Shimmer3 IMU unit was intially put on a desk and then lifted off the desk and rotated around each of its three axes. In between each axis rotation, the Shimmer to be placed level on a workdesk to show a stationary duration of the device.

The kinematic data was passed with the 9DoF-to-IMU algorithm, which can be found in our Consensys software program application. This algorithm produced 9DoF Quaternion data from the calibrated Low-Noise Accelerometer, Gyroscope and Magnetometer data.

Magnetometer

The Shimmer3 IMU unit was originally placed top top a desk and then lifted turn off the desk and also rotated around each that its three axes. In between each axis rotation, the Shimmer to be placed level on a workdesk to show a stationary duration of the device.

The kinematic data was passed v the 9DoF-to-IMU algorithm, which can be found in our Consensys software application. This algorithm created 9DoF Quaternion data from the calibrated Low-Noise Accelerometer, Gyroscope and Magnetometer data.

EMG

Using the Shimmer3 EMG unit a subject linked two EMG electrodes to the forearm and also to the biceps that their right arm when performing a variety of sustained muscle contractions over a two minute recording period. A referral electrode was associated to a boney obtrusion top top the wrist.

Respiration

Respiration is figured out by impedance pneumography which measures the impedance changes throughout the lungs during the inhalation/exhalation cycle. Note: using the Shimmer3 ECG in respiration setting introduces some interference on all of the ECG channels.

The Shimmer an equipment was put on a desk and also connected to a topic using the adhering to electrode placement:

White: best Arm (RA) ~ above the midaxillary line of Vertebrate 6 (V6)Black: Left eight (LA) top top the midaxillary line of Vertebrate 6 (V6)Green: ideal Leg Driver (RLD) ~ above the appropriate hip bone.Red: Left foot (LL) over the left i know good bone.Brown: Vx (where x is 1, 2, 3, 4, 5, or 6) left the the xiphoid process.

While at rest the subject breathed normally for a 2 minute period and in ~ the end of each minute performed 3 pronounced inhalations and also exhalations.

GSR

Using the Shimmer3 GSR+ unit a subject linked the GSR electrodes to the index and middle finger top top the left hand and the PPG probe onto the left ear lobe.

During the very first minute of data recording, the topic was sit down and also during the second minute, the subject was walking.

The PPG data was passed through the PPG-to-HR algorithm, which can be found in ours Consensys software application. This algorithm converts the PPG signal come a heart price (bpm). The love rate has a value of -1 for the first few samples together the algorithm beginning a cultivate period.

Optical Pulse PPG

Using the Shimmer3 GSR+ unit a subject linked the GSR electrodes to the index and also middle finger top top the left hand and the PPG probe top top the left ear lobe.

During the first minute the data recording, the subject was sit down and during the 2nd minute, the topic was walking.

The PPG data was passed through the PPG-to-HR algorithm, which have the right to be uncovered in our Consensys software application application. This algorithm counter the PPG signal come a heart rate (bpm). The love rate has actually a value of -1 for the first few samples together the algorithm start a maintain period.
