A new sensor and joint motion monitoring system to remind users to exercise regularly

Perhaps you have had the experience of sitting still and using a computer or mobile phone for a long time, and end up feeling pain in your shoulder, neck, waist and back. A sensing system that can monitor joint motions and remind you to move and stretch regularly may help keep your joints healthy. A research team led by scientists at City University of Hong Kong (CityU) developed a new sensor with a unique composite and kirigami structure, which can distinguish different modes of joint motions.

Animal experiments demonstrated the need for new cochlear implant design for localising sound directions

Cochlear implants help deaf patients in hearing, yet the current technology remains far from perfect. A research team led by scientists from City University of Hong Kong (CityU) has shown that neonatally deafened rats could be trained with cochlear implant stimulation to restore the ability to locate the directions of sound origins.

CityU’s new, easily assembled fast-track ventilation system can thoroughly filter Covid-19

As there are still hundreds of thousands of new Covid-19 cases every day around the world, not to mention the continuous spread of variants, scientists are trying their best to combat the epidemic. A research team at City University of Hong Kong (CityU) recently developed a new ventilation system that can thoroughly filter viral particles and quickly stop the spread of Covid-19 in the air at low cost.

World’s first discovery of liquid directional steering on a bio-inspired surface
