Wireless Body Sensor Networks: Higher Efficiency, Lower Power, Better Privacy!

Introduction According to a recent report from the National University of Singapore (NUS), researchers have invented a new method for connecting wearable devices. This “wireless body sensor network” increases the signal strength for data transmission by a factor of a thousand compared to traditional technologies, which also means that the battery life of all devices … Read more

Inspired by Batfish, Chinese Research Team Develops Miniature Deep-Sea Morphable Robot Capable of Swimming, Gliding, and Crawling in the Mariana Trench

At the depths of the Mariana Trench, where the pressure is equivalent to a one-ton rhinoceros standing on a fingernail and the temperature approaches freezing, deep-sea robots that could reach this area were mostly large rigid submersibles weighing several tons. For small robots under one meter in length, the extreme environment here was once a … Read more
