future electrical and electronics technologies

  1. 1. "Light can carry more data than a wire, and it takes less energy to transmit photons than electrons,"
  2. 2. Light is much more efficient at transmitting data than electricity can through wires, but getting it to work reliably in a computer has been somewhat problematic. A team of engineers have just announced a new “optical link” device made out of silicon that is able to bend light at right angles, which is an important advancement toward replacing electric wires in computers with optics .
  3. 3. Wearable health-monitoring devices represent an exciting opportunity in healthcare. Armed with tools to track their own conditions, patients could be empowered to take responsibility for their own health. And rather than getting small glimpses during infrequent checkups, physicians could be provided with a steady stream of data about how their patients are doing.
  4. 4. Wireless power transfer or wireless energy transmission is the transmission of electrical power from a power source to a consuming device without using solid wires or conductors. It is a generic term that refers to a number of different power transmission technologies that use time- varying electromagnetic fields. Wireless transmission is useful to power electrical devices in cases where interconnecting wires are inconvenient, hazardous, or are not possible. In wireless power transfer, a transmitter device connected to a power source, such as the mains power line, transmits power by electromagnetic fields across an intervening space to one or more receiver devices, where it is converted back to electric power and utilized.
