Hi I am a PhD student at DTU, Denmark. My research focus is about precision vibroacoustic measurement, especially for small objects. For my research, I need a sensor to measure curved surface in a tight space, e.g. inside a hearables. The sensor has to be super tiny, preferably 3-axis, light-weight, high sensitivity, low noise, and has wide working frequency.
I am planning to use the bma580, which is currently the smallest MEMS accelerometer in the world. The sensor is marketed to be featured in hearables as vibration-induced voice sensor. I thought I could use it as a sensor for high precision vibroacoustic measurement. I am familiar working with vibration measurement tools like conventional piezo crystal accelerometer or LDV (laser doppler vibrometer) for more than 8 years, but I have never handled digital MEMS sensor previously.
Questions:
To approximate a point source, is it possible to connect the chip directly to thin wire? I would like to put the chip directly to a surface. This is for a research purpose, so I expect not to follow the standard guidance.
If yes for question nummer 1, is it possible to have a "detached" version of the shuttle board? the chip is not mounted to the board, but rather connected to via thin wire. What is the risk of having the capacitors and resistors slightly away from the chip?
In my PhD programme, I need to do an external research for around 4 months. I really want to learn deeper about this topic. Is it possible for me to be an external research at Bosch on early next year 2027?
Best regards,
Teguh
