    Piezo question

    I got some piezo discs, hook one up to my multimeter, apply pressure to disc, get voltage, switch over to measure current, get nothing. I repeat same process with a second and third disc, and get same results. Ive seen people use these, not mine, but these same piezo discs to power an led hooked...

    Will this simple Piezo circuit work?

    Hi guys, Just wondering if this simple circuit will work as I expect it to. So this is for an engine, I'm utilizing multiple Piezo igniters to create a spark plug and I'm trying to figure out if this will work. I understand that this would be pretty easy to test I just don't have the...

    How Can I submit a novel patentable design idea to a company?

    Hi there, Recently, I have designed a new charge amplifier than can be used to implement a precision and low-cost interface for piezoelectric sensors. I have published an article about the novel proposed circuit in IEEE Sensors Journal. ( A brief information about the new proposed circuit has...

    Interfacing circuit for Piezoelectric vibration sensor to detect shock

    I want to detect the mechanical shock of a machine. To measure the vibrational shock I am using Minisense 100 Piezoelectric vibration sensor. I have done the feasibility test using it and it is giving output as expected. I have observed on the oscilloscope output frequency for all type...

    Help with basic piezoelectric generator circuit design

    Hello, I want to experiment with the properties of piezoelectric generator devices. I am looking to get a few PZT devices where I can stress / impact the material to produce current. I have concept to use multiple PZT devices where they will be stressed simultaneously. The PZT devices output a...

    High Power Piezoelectric Ultrasonic Transducer Driver

    Hi Everybody, I am working on a project that needs to drive 5 (175 watts) Piezoelectric Ultrasonic Transducers, the system needs to output clear ultrasonic sound at 40 kHz (precise sine wave) The system needs to produce a very clear sound (of course not for the human ears) of 40 kHz sine wave...
