Credit: NPJ Parkinson Disease (2021) DOI: 10.1038 / s41531-021-00171-0 EPFL scientists have developed algorithms that, when combined with wearable sensors, could help clinicians monitor the progression of Parkinson's disease and assess the effects of drugs commonly used by people with this neurodegenerative disorder. Parkinson's disease affects neurons in an area of ​​the brain that controls movement and causes tremors, difficulty walking, and other motor problems. Doctors caring for people with Parkinson's must be able to assess t

New algorithms combined with wearable sensors to track symptoms of Parkinson's disease

Parkinson's disease, a brain disorder that affects neurons in an area of ​​the brain that controls movement and causes tremors, difficulty walking, and other motor problems. As the disease progresses, people can have difficulty walking and speaking. To assess the severity of symptoms, clinicians rely on a handful of tests, such as: B. those that measure the walking speed - or how fast people walk. These tests are usually done in the clinic every few months. Various factors can affect the results, including the experience of the person performing the assessment. Usually walking speed is the sixth sign of life and is also related to life expectancy. For example, if you go faster, you can count on a longer lifespan. In a new study, EPFL scientists determine how the walking speed is influenced in Parkinson's disease. 27 people with Parkinson's disease were included in the study. They were then fitted with a foot-worn sensor that recorded how fast they were

Wearable sensors that detect gas leaks

The development of a sensor that can quickly detect toxic gases or biochemicals remains a major issue in the public health, environmental surveillance, and military sectors. Recently, a research team at POSTECH developed an inexpensive, ultra-compact portable hologram sensor that instantly notifies the user of the detection of volatile gases. A joint research team led by Professor Junsuk Rho from the Department of Mechanical and Chemical Engineering and Dr. Inki Kim from the Department of Mechanical Engineering with Professor Young-Ki Kim and Ph.D. Candidate Won-Sik Kim from the Department of Chemical Engineering at POSTECH has integrated the metasurface with the gas-reactive liquid crystal optical modulat
