BEIJING, May 5 (Xinhua) -- The following are the highlights of China's key technology news from the past week:

LONG MARCH-11 CARRIER ROCKET

China plans to launch a Long March-11 carrier rocket at sea this year, which is expected to lower the cost of entering space.

The rocket has been named "CZ-11 WEY" under an agreement between the China Academy of Launch Vehicle Technology, China Space Foundation and a Chinese automobile producer.

3D TECHNOLOGY CONSERVATION

Researchers are using 3D scanners to collect data about the size, color and structure of the Nanchan Temple on Wutai Mountain in northern China's Shanxi Province.

They plan to create a digital archive for the temple, which is the oldest extant wooden building from the Tang Dynasty (618-907) in China.

CARDIAC PACEMAKER POWERED BY HEARTBEAT

A research team has developed an implantable medical device that can harvest energy from heartbeats rather than batteries, according to a recent report published in the journal Nature Communications.

The cardiac pacemaker was designed on the basis of an implantable triboelectric nanogenerator, which can achieve energy from heartbeats and convert the energy to electricity for powering pacing pulses.

YUANWANG-7 SPACECRAFT TRACKING SHIP

China's spacecraft tracking ship Yuanwang-7 is sailing to the Pacific Ocean, beginning its first maritime space monitoring mission this year.

As a part of China's new generation of spacecraft tracking ships, Yuanwang-7 can perform tasks in the Pacific Ocean, the Indian Ocean and the Atlantic Ocean within 60 degrees north and south latitudes.
