Under a Defense Advanced Research Projects Agency program, the company sought to produce 20 milliwatts
of continuous wavelength and power with an initial goal of attaining 40 percent wall plug efficiency.
The types that can reach aeroplanes are much more powerful and dangerous and are for sale online at strengths of up to 500 milliwatts
The output of the micro-generator can easily cover the power needs of intermittent radio sensor systems such as Wireless HART, SP-100 and Wi-Fi in industrial applications, but its output impedance is too high to supply the 10s to 100s of milliwatts
required by sensor nodes during data collection and transmission.
That equals 36 microwatts--microwatts, not milliwatts
. A mainline pressure transducer can draw 5 milliamps at 5 Vdc, equaling 25 milliwatts
of required power.
Carrying this analysis on to the sphere of TVs, phone chargers, PCs and so on, each consuming power measured in milliwatts
, and the result is a thin line at the base of the bar chart I am constructing.
The transmitter consumes 8.8 milliwatts
, or about one-third as much power as other implantable transmitters, while transmitting 10 times more information.
The program goal is to develop a one cubic centimeter AlphaVoltaic (AV) battery that can deliver 35 milliwatts
continuously for many months to many years.
About 70 to 100 milliwatts
is generated when a person passes through a ticket gate.
According to PolyFuel, the new 45-micron hydrocarbon membrane's peak electrochemical performance in passive hardware at 40 degrees Celsius is 80 milliwatts
per square centimeter (mW/cm-squared) of membrane at 0.28 volts, versus 60mW/cm-squared for the 62-micron membrane -- a 33-percent improvement the company said results directly from the 27-percent reduction in thickness.
The first microbial fuel cells produced between 1 and 40 milliwatts
per square meter (mW/[m.sup.2]) of anode electrode surface area, says Logan.
It has power output of 100 milliwatts
and is capable of powering an MP3 music player for 20 hours on a single 2 cc charge of concentrated methanol, Toshiba said.
The OV2620 requires only 132 milliwatts
of power in active mode and 33 microwatts of power in standby mode, making it ideal for portable applications.
