Intersil and Nextreme Thermal Solutions Develop Comprehensive
Reference Design for Energy Harvesting Applications Precision Amplifiers and Switches From Intersil Enable Self-Powered Wireless Strain Gauge Measurements
MILPITAS, CA, Nov 10, 2011 (MARKETWIRE via COMTEX) --
Intersil Corporation (NASDAQ: ISIL) and Nextreme Thermal Solutions,
an innovative leader in cooling and energy harvesting solutions, have
developed a reference design for a self-powered, wireless strain
gauge module using precision amplifiers and switches from Intersil.
Powered by thin-film thermoelectric technology, the gauge measures
strain in locations that are not easily accessible, such as inside
walls, in pipes, or under bridges, then transmits the measurements to
a remote, easily accessible receiver.
The module consists of a strain gauge, an Intersil ISL28133 chopper
amplifier, an Intersil ISL54051 low on-resistance switch, and an
Si1012 wireless module. A 100uA continuous current draw is sustained
by the Nextreme TherMobility thermal energy-harvesting unit, and
excess energy is stored in a capacitor until required. Once the
module is installed, it will operate untouched throughout its
The new reference design will be demonstrated at the Nextreme booth
at the Energy Harvesting & Storage USA conference in Boston on
November 15 and 16. The reference design and more information about
the components used are available from Intersil Corporation's website
and Nextreme's site at
The Intersil-Nextreme collaboration represents the first step in a
joint program of wireless sensor network development for energy
harvesting and ultra-low power systems.
Chopper Amps Feature Low Power, Low Voltage Offset Over Temperature
The Intersil ISL28133 chopper-stabilized op amp was chosen for this
design because it is the lowest power op-amp of its type, requiring
only 18uA during operation. Low power and low voltage offset over
temperature (75nV/oC) and time are key features for energy harvesting
applications, and the ISL28133 is a proven performer in both of these
areas. In addition, the small size (1.6mm x 1.6mm uTDFN package) of
the ISL28133 and 1.8V supply voltage makes it an ideal choice to be
paired with small, low powered sensors, which may need to be powered
by energy harvesting devices. As an alternative design choice,
Intersil also has a lower noise chopper stabilized op amp, the
ISL28134, with a 15nV/oC voltage offset drift over temperature.
