TECHNOLOGY

Piezonix’s sensor-to-circuit integrated system can collect, compute and store historical statistics of a structure’s strain-rate and levels at operational power limits not possible with any competing heath monitoring sensor technology. By operating on picowatts to nanowatts of power, Piezonix’s self-powered sensors can function continuously by scavenging energy from, for example, a miniature piezoelectric transducer. Two issued patents US 7,757,565 and US 8,056,420 and one pending patent application no: 61/602,247 protect the technology.

Innovation: Piezo-Floating-Gate (PFG) Technology

Eliminate power regulators, energy storage, data converters, RAMs and digital signal processors. Use the physics of the device and the structure to perform computation and storage.

PFG_Tech_1

 

•Piezoelectric ceramics and polymers can generate high-voltages for low strain-levels but at ultra-low-driving currents.

•Hot-electron injection in sub-threshold floating-gate memories require high-voltages but can operate at ultra-low-currents.
