I am working on a project on pressure based sensor and I need to use Velostat pressure mat to detect pressure. I want to use other technologies which will help to detect pressure.
In addition to piezoelectric sensors, you can also use other types of pressure sensors which are called optical micro-resonators. For more information you can find the following article which is very helpful in this regard:
" Ultra-sensitive planoconcave optical microresonators for Ultrasound sensing "
