I dont known anything, but a Knowles MEMS microphone on digikey is $1 qty 1 [0]. A few 100 uA consumption. I'm pretty sure there is space for disruption here.

- AstralStorm 9y agoYes, MEMS microphones of ok quality are a few dollars but you need a few or an array (worse quality ones are cheaper), balanced armature of good quality are not cheap. This one has really bad SNR (-42 dB) The space requires micromechanical research and manufacturing expertise. Good luck "disrupting" it.
- blattimwind 9y ago- Does not work with the available voltage - Far too big - Requires about 1/3 of the entire power budget > I'm pretty sure there is space for disruption here. [hackernews noises]
