Smart Ambulatory Device designed with FlexiForce™ Sensors

Background:

According to the present edition of World Population Ageing, globally, the number of older adults (aged 60 or above) is expected to more than double from 841 million people in 2013 to more than 2 billion in 2050. This increase will correlate to a rise in disability, predominantly motor disabilities amongst the adult population. The need for smart ambulatory devices is increasing. These devices will help disabled adults regain "normal gait" and increase their quality of life.

Challenge:

Designing a cost-effective, smart ambulatory device that assists the disabled and helps them regain confidence and independence in their mobility and daily lives.

Solution:

Researchers at the Centro De Investigación y De Estudios Avanzados Del Instiuto Politécnico Nacional created a smart walker prototype using FlexiForce™ sensors to help patients achieve a more "natural" gait. The device was designed by adding two FlexiForce sensors to the hand supports of a walker and two small motors of DC voltage to the front wheels. The walker's speed is controlled by a microcontroller that uses a pulse width algorithm. The microcontroller communicates via bluetooth, translates the force applied and sends it to the laptop for processing. The changes in the force may be indicative of a neuromuscular disorder or injury. The quantitative data resulting from the load forces allows the user or a doctor to examine and identify irregular load ranges and rhythms, which can be attributed to certain diseases. This smart device allows for a better diagnosis and treatment plan.
