They introduced a nail sensor that serves to help patients with Parkinson's



(Special thanks) At the opening of the CES 2019 event in Las Vegas, a finger sensor was introduced to monitor finger movement. It is a prototype and would serve to diagnose and evaluate the treatment of some diseases, such as Parkinson's.

The IBM Research prototype serves to control human health. Measure continuously the way a person's nail doubles and moves around in daily activities. It is a strategic indicator of grip strength.

The grip strength is a metric that serves to measure different variables in health. It is associated with the efficacy of medication in individuals with Parkinson's disease. It also serves to study people with schizophrenia, older adults or individuals with cardiovascular problems.

How the nail sensor works

It is a small portable wireless device that uses AI and is located at your fingertips. They say the company is the first prototype of its kind.

"When we go from day to day doing manual things, opening a door or putting a key in a lock, there is a tiny displacement of less than a micrometer, that is, 100 times smaller than the diameter of a hair. very fundamental about our health, "said Darío Gil, director of operations for IBM Research Infobae.

So if a person had a neurodegenerative distortion, such as Parkinson's, certain variables could be anticipated.

The sensor is composed of meters connected to the nail and a small computer that shows the voltage values. Collect data from the accelerometer and connect to a smart clock.

By measuring the nail and curve movements, the device collects data that is studied by AI algorithms to indicate patterns. These results can give physicians a "snapshot" of a person's grip strength. This is how the specialist can provide more personalized treatment recommendations.

This device uses machine learning models to evaluate bradykinesia (ie slow movement), tremor and dyskinesia (abnormal and involuntary movements).

Currently, methods for measuring the progression of some diseases are based on connecting sensors in the skin to measure variables with movement by studying the health of muscles or nerve cells.

However, in older patients, these types of sensors, based on the skin, usually cause problems, such as infections.

To create the prototype, the researchers interacted with objects through tactile pressure detection, temperature and surface textures, for example.

The Michael J. Fox Foundation, which investigates Parkinson's disease, donated the company for research to find more effective treatments.
