Hi to all!
I am supposed to design an electronics system that uses Acoustic Emission (AE) transducers to detect cracks and damages in materials. In essence, I need two paths : transmit (TX) and receive (RX).
-> For the TX path, the transducers act as actuators. They must be activated with a sine wave pulse and they emit acoustic signals in the material.
-> For the RX path, the transducers act as sensors. They receive acoustic signals from the material, either passively created by the damage or actively by the actuators.
The problem is that I have never designed something like that and I would like some help, from anyone that knows, mainly for the RX path. Does anyone know what analogue front-end is required for the AE sensors, between the devices and the A/D converter? Some amplification stage maybe? For the TX path, I intend to use a microcontroller in order to create the required pulses.
I would appreciate any help.
