BEIJING, April 15 (Xinhua) -- The following is a summary of recent science and technology news of China.
LIQUID METAL FOR FLEXIBLE SENSORS
Chinese researchers have optimized the design of liquid metal to improve the sensitivity of stretchable sensors, according to Chinese Academy of Sciences.
The experiment results showed that the sensors worked as usual with 590 percent stretch, 270-degree torsion or 180-degree bend.
The new design provides a solution for accurately measuring people's fingers' and wrists' movements.
SHENZHEN R&D SPENDING
China's tech hub Shenzhen saw a robust growth in research and development investment in 2018, which accounted for 4.2 percent of the city's GDP last year, according to Wang Weizhong, the city's Party secretary.
VR SURGERY TRAINING
A hospital in Beijing is pioneering the use of virtual reality (VR) technology to help train doctors to perform heart surgeries.
Researchers have built a 3D heart model with typical CT images of heart disease patients. They routed the 3D model to a head-mounted display through VR software developed by a Hangzhou company.
