Radiant Unveils Test Platform at Ferroelectric Meeting in Tel Aviv
Since its inception in 1988, the Albuquerque, New Mexico-based
company has been developing characterization equipment for
non-volatile memory technologies, non-linear electromechanical
materials, MEMS, actuators and sensors.
Its Precision Multiferroic II ferroelectric tester features a frequency
rating of 270KHz at +/-100V built-in to the system, making
testing of thin films and bulk ceramics a fast and simple process.
With the addition of extra fixtures, the Precision Multiferroic II can
measure pyroelectric properties, magneto-electric properties,
transistor characteristics, cryogenic properties, bulk ceramic and/
or thin film piezoelectric properties.
Radiant Technologies to unveil new piezoMEMS technology at IMF
meeting in Israel
Last month in Tel Aviv, attendees at the 15th International
Meeting on Ferroelectricity were able to check out the latest
development in piezoMEMS analysis by Radiant Technologies.
The high-resolution angstrom-level measurement platform is an
exciting step forward in the development and testing of thin film
piezoMEMs devices, says the company, known as a leading developer
in the field of ferroelectric, magnetoelectric, pyroelectric,
transistor material and piezoelectric testing.
The analyzer not only measures piezoelectric properties of actuator
and sensor elements of a commercial product, it will communicate
with the product's electronic logic, talk to embedded
microprocessors, supply asynchronous voltages and pulses and
measure sensor frequencies. The system is designed to bring
new capabilities to the field of ferroelectricity, presently a focus
technology in scientific research and development for electronic,
semiconductor and, lately, even hydrogen production applications.
Ferroelectricity is a characteristic of certain materials that
have a spontaneous electric polarization that can be reversed
by the application of an external electric field, making it a prized
attribute to be able to detect, manipulate and control.
The accessory adds several items to the tester. Among them are
a shield box which serves as a sample holder that shields the
sample electrically while also mounting magnetic field sensors
directly at the sample location. Other items include a Lakeshore
MH-6 Helmholtz coil for applying small magnetic fields up to 50
Oersted and a Lakeshore Hall Effect magnetic field sensor used
for calibrating the test fixture.

The company's Magnetoelectric Bundle offers researchers a
complete hardware and software platform to characterize magnetic
coupling of multiferroic or magneto-piezoelectric devices.
The bundle hooks up to existing coils on the market such as
GMW and other manufacturers.
IMFwas held on March 26-30 in Tel Aviv. A keynote presentation
was made by Avner Rothschild of Technion (Israel Institute
of Technology) on the application of ferroelectricity to producing
green hydrogen by splitting water molecules into hydrogen and
oxygen to accomplish electrolysis. A spinout company H2Pro,
has been established to commercialize Technion's research,
aiming to produce green hydrogen at $1/kg by the end of this
decade.
