How often do you get lost in a city even when using GPS? Has a taxi hailed using a mobile app been unable to find your correct location? The reason is because GPS has an average error of 10 to 30 meters, and other indoor navigation techniques using WiFi and Gateway have positioning errors, too. […]
Ultra-Thin Sensor Makes Inflammation Testing And Curing 30 Times Faster
Different from the inorganic counterparts like silicon, organic semiconductors can operate under bending or stretching. Usually a thinner film can have stronger capability to bend. Other than bending, a thinner or smaller device can also offer a faster response time which is particular important for sensor application if immediate information is needed. These ultra-flexible sensors […]
Novel Solution To A GPS Blind Spot For Safer And Smarter Driving Experience In Multilevel Road Networks
Multilevel road networks such as flyovers and overpasses are built in large cities to solve traffic congestion. Rapid, accurate identification of the road level in a multilevel road network is important to make driving safer and more comfortable. Vehicle drivers relying on GPS navigation who accidentally drive onto a flyover with the intention only to proceed on […]
Innovative And Ideal Liquid-Repellent Surfaces Developed By HKU Scientists
On liquid-repellent surfaces, liquid droplets bounce away instead of being stuck. These surfaces are important in many fields, such as water-repellent clothes and anti-fouling kitchenware. Used as drag-reduction coatings for water vehicles, these surfaces can even help with speeding up cargo ships and military equipment so as to save energy. The dream of research and […]
