technology is leaving the laboratory to become commercial PiezoMEMS Analyzer. Much thicker bulk capacitors are being
embedded as actuators and sensors inside their own electronic circuitry. Multidisciplinary teams of mechanical,
electrical, and reliability engineers now work alongside materials engineers to
create new and novel devices. Classic
engineering tools such as impulse response, impedance analysis, and resonance characterization
must be integrated with traditional polarization, piezoelectric, pyroelectric,
and magnetoelectric measurements. To
control circuits containing embedded ferroic capacitors, asynchronous or
semi-synchronous digital and analog functions must run independent-of or in-parallel-with
crystal-clock-controlled ferroic measurements.
Communication with embedded controllers and custom digital circuitry is
critical. Together these requirements demand
an extremely complex test environment.
Radiant Technologies’ Precision PiezoMEMS Analyzer integrates digital, analog, and communications circuit functions
with the existing non-linear materials measurement capabilities of the
Precision Multiferroic Non-linear Materials Tester, all supervised by Radiant’s
Vision programmable test environment. The PiezoMEMS 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
