Using MEMS Accelerometers as Acoustic Pickups in Musical Instruments

MEMS microphones have begun to dominate the broad consumer market, including cell phones, Bluetooth headsets, personal computers, and digital cameras. Now, key technologies used in MEMS accelerometers can bring a new dimension to acoustic transducers. Low-g accelerometers don't suffer from traditional feedback problems, and show clear potential as high-quality acoustic pickups for musical instruments.

Intesesting, ordered ADXL001 samples with exactly this application in mind (and described this with my order) month ago (to be exact, on June, 19 last year)and now I read this article ... bedides string instruments this might be also usefull on drums ... so, did you guys had the same idea or just heard from your sample department (so I might had applied for a job at AD at that time ...). I'd like to stay in contact with you guys, feel free to keep me updated (r&d@edumotion.de) ... BR, MIchael

With the limited frequency range you should try making a prototype for double bass. There range is considerably less than that of a guitar and they are notoriously difficult to capture. Most player don't like using the pezio mics so this would be a great alternative

What would be the effect of radiation on MEMS device. Can they be hardened against low levels (say 10 to 100 millirems?)

What is decay/damage mechanisms, and what rates.
