A Field Deployable PiezoElectric Gravimeter (PEG)

Conventional gravimeters typically measure the amount of the opposing forces required to suspend an object or by monitoring an objects freefall rate. This innovative technology uses piezoelectric instrumentation in a completely new way, reversing their role. The piezoelectric transducers are...

Accelerometer and Gyroscope Designs Based on CNT Tape

NASA's accelerometer was designed to address the shortcomings of conventional piezoelectric-based accelerometers that are made from ceramic materials such as barium titanate (BaTiO3) or lead titanate (PZT). These materials are inherently brittle, have a tendency to be noisy, have difficulty sensing...
