[Jason] has continued to plug along with his sonar build and recently showed up a monostatic active sonar using a piezo element and microphone. Regular readers will remember [Jason’s] experiments from ...

In this experiment we are going to work with a sensor which is a resistor that depends on light. In a dark environment, the resistor will have a very high resistance. As photons (light) land on the ...

These small and strong materials offer a wide frequency range, suiting a variety of applications and specific design needs without sacrificing performance. Electronic engineers are no strangers to odd ...

(A) Schematic comparison of the puncture process with and without axial vibration, including 3 stages: pre-puncture (contact compression), puncture (membrane rupture), and post-puncture (insertion ...

Albuquerque, N.M. -- For the past three years a Sandia research team headed by Mat Celina has been investigating the performance of various piezoelectric polymer films that might one day serve as ...
