SENSORES INERCIALES ISEN - STT

La ingeniería Inercial en 3D al servicio de la medicina, Ingeniería y deporte de una manera sencilla, inalámbrica y en tiempo real.

Ciencia en Movimiento

DESCRIPCIÓN GENERAL ISEN es un revolucionario sistema de medición inercial en 3D conformado por 1 acelerómetro triaxial, 1 giroscopio y 1 magnetómetro, que miden la orientación angular, velocidades angulares y aceleraciones en las 3 dimensiones en tiempo real y de manera inalámbrica, transmitendo los datos al computador de escritorio, portátil o smartphone.

Cuales son sus campos de aplicación? ORTOPEDIA Y REHABILITACIÓN ANÁLISIS DE MARCHA BIOFEEDBACK

DEPORTE BIOMECÁNICA E INVESTIGACIÓN INGENIERÍA PARA DESARROLLADORES

Ciencia en Movimiento

ORTOPEDIA Y REHABILITACIÓN:

ISEN es ideal para usarse en rehabilitacion usando Biofeedback, dado que se pueden programar alarmas sonoras cuando el paciente está por fuera de cierto rango articular, o cuando alcanza determinado objetivo.

Isen permite hacer evaluaciones de cada articulación por separado.

Ciencia en Movimiento

ANÁLISIS DE MARCHA:

Con 7 Sensores Isen es suficiente para realizar un análisis tridimensional de la marcha de la cinemática de la pelvis, cadera, rodilla y pie en los planos sagital, frontal y transverso. Se evita el uso de cámaras tridimensionales, ahorrando también gran espacio y costos respecto a un laboratorio de marcha. Isen se puede sincronizar con electromiografía de superficie y plataformas de fuerza triaxiales.

This SDK can be integrated easily in .NET and C++ enviroments. It allows to fully control the STT-IBS through high-level functions such as connection/disconection of gyros, start/stop recording, data recovering in real time TXDWHUQLRQV'PDWUL[URWDWLRQ VHQVRUFRQ¿JXUDtion (update, frequency, calculations on sensor), etc. Multiple sensors can be connected simultaneously, as the developer can get an instance of the API class for each sensor. A user manual documenting all functions is provided, as well as full-source code examples in C# and C++ explaining the usage of core functions.
