(PhysOrg.com) -- To improve transmission speeds, the Internet has transitioned over the years from one using copper to fiber optic cabling. Unfortunately, this has caused a bottleneck to occur where the light signals meet ...
(Phys.org) —In today's wireless communication systems, the wireless signals are non-chaotic, meaning they have a well-defined period and frequency. Non-chaotic wireless signals are used in many applications, such as satellite ...
(Phys.org)—While some advanced humanoid robots already look eerily lifelike, robots in the future may actually become partly alive. Currently, researchers are working on integrating living cells and other biological components ...
Researchers have used 3-D printing and nanotechnology to create a durable, flexible sensor for wearable devices to monitor everything from vital signs to athletic performance.
