During the last two decades, human motion analysis systems have been developed using various technologies, such as camera-based, magnetic, ultrasound, electro-mechanical systems. An important general drawback to these systems is that the subject can only move within a closed and constrained space, typically a radius of not more than a few feet. The recent emergence of body-worn sensor technology has provided new avenues for measurement and assessment of the physical activity and daily motor function (e.g. postural transition, walking, etc.) during everyday life. Devices based on body-worn sensors are highly portable, and do not require supporting stationary units such as transmitters, receivers, or cameras. Additionally, due to recent advances in MEMS technology, these sensors are significantly cheaper to manufacture than sonic, magnetic and optical motion capture systems. We have almost a decade of experience in the development of algorithms and ambulatory devices based on the body-worn sensor technology for human movement analysis, and in particular, for the evaluation the risk of falling and fall prevention among elderly subjects and diebetic patients, who suffer from balance instability.
Physilog is an ambulatory system based on body-worn sensor, has been designed for the analysis of locomotion. It includes four body-worn sensors attached on each shank, thigh and one sensor attached to subject's lower back. This configuration enables to extract the spatio-temporal parameter of gait as well as dynamic balance during walking and in free condition.
MotionNode is a 3-DOF inertial measurement unit (IMU) for use in motion sensing applications. This sensor module enables extracting the 3D motion of body segment in real time.
Zephyre - BioHarness is an ambulatory device based on body-wron sensor. It captures comprehensive physiological data on the wearer, eliminating the need for multiple devices. The robust BioHarness™ enables genuine real world monitoring of human performance and condition – giving you a vital advantage
