future electrical and electronics technologies

6. "Light can carry more data than a wire, and it takes
less energy to transmit photons than electrons,"

7. 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 .

8. 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.

11. 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.
