>> PSIKICK - ULTRA LOW POWER MICROCHIP FOR IoT
With the promise of 20+ billion connected devices in IoT - powering them is
A Virgina based started called
is development a microchip for simple sensing tasks - that depending on the
application, consumes a fraction of the power of comparable chips on the
market. This new kind of low power chip could be revolutionary within the
A brainchild of two MIT graduates,
David Wentzloff and
Benton Calhoun - the startup plans to start selling the first chips
by 2015. Wentzloff stated that the power consumption is between 0.1 and 1.0
percent - requiring so little power means the chips can function based on
power that can be scavenged without the use of a battery.
Normally, transistors in circuits are either on with current flowing through
them; or off with no current flowing through them - depending on whether the
voltage supply is above or below a certain threshold value. In reality,
though, a small amount of current can leak through most transistors even
when they are technically switched off.
Energy could come from a small solar panel; an antenna that collects ambient
radio wave energy; a thermoelectric material that absorbs body heat or even
piezoelectric devices that collect energy from simple movement. It is this
combination that if can be tailored into the design of solutions that could
revolutionize the IoT sector.
