Gait patterns in unstable older patients related with vestibular hypofunction. Preliminary results in assessment with time-frequency analysis.

Background: Gait instability and falls significantly impact life quality and morbi-mortality in elderly populations. Early diagnosis of gait disorders is one of the most effective approaches to minimize severe injuries.

Objective: To find a gait instability pattern in older adults through an image representation of data collected by a single sensor.

Machine Learning Identification of Piezoelectric Properties.

The behavior of a piezoelectric element can be reproduced with high accuracy using numerical simulations. However, simulations are limited by knowledge of the parameters in the piezoelectric model. The identification of the piezoelectric model can be addressed using different techniques but is still a problem for manufacturers and end users.
