What is an Inertial Measurement Unit?
An IMU, short for Inertial Measurement Unit, is a device capable of recording the angular velocity and acceleration of an object or person. These devices have a wide range of applications, especially in fields involving inertial navigation, such as aviation, maritime vessels, or spacecraft.
In this article, we focus on the use of STT’s IMU in fields where inertial motion control related to the human body is required. This type of measurement is particularly used in sports like athletics or cycling, allowing for full and professional biomechanical assessments to improve performance.
What does an IMU sensor measure?
As mentioned, an IMU sensor is highly capable of measuring data associated with a person’s movement, both in terms of acceleration and in relation to angular velocity recording.
The large amount of data collected on each movement made by the person under study allows us to analyse them in detail in order to carry out a detailed analysis of their movements.
Characteristics of the STT IMU sensor?
The IMU STT-IWS inertial sensor has powerful features that make this sensor a professional tool for in-depth motion analysis.
Wireless wifi sensor
The communication of the sensors is done by wifi system, with bands ranging from 2.4 GHz to 5 GHz, making them very versatile sensors.
Internal processing capacity
The internal sensors are calibrated in such a way that they provide real-time orientation, acceleration and altitude measurements.
Data synchronisation
Samples collected by the sensor are each time-stamped, so that data from several sensors are synchronised and individually identified.
IMU is multi-sensor
The STT inertial sensor contains several internal sensors, such as a triaxial gyroscope, triaxial magnetometer, accelerometer, triaxial, barometer, humidity sensor and internal temperature sensors.
400 Hz frequency sensor
The sensor can be configured to capture data at different frequencies, ranging from a few hertz up to 400 Hz, enabling exceptional data transmission speed.
Internal memory
While the sensor can transmit data via Wi-Fi, it also has internal memory for data logging, allowing it to operate outside of Wi-Fi range.
Integrable sensor
The sensor can receive analog data through up to 8 channels. Additionally, it supports serial port connections for devices such as GPS receivers.
Highly accurate IMU
IMU sensors are known for their high level of precision and accuracy.
Developer-friendly options
Open-source tools are available to configure the sensors and store data in CSV format.
