@Kirsty_Gardner_ @nnjeorje @eceroyal13 @Mutant_Boris@kwalus@CanforCorp@DustCount The sensing mechanism is based on our inkjet printed IDTs (drive IDTs and receiving IDTs). When there is a change in mass due to the PM, the frequency of the input wave will change and be sensed by the receiver IDTs. The readout is a portable monitor for real-time changes in PM.
@Kirsty_Gardner_ @nnjeorje @eceroyal13 @Mutant_Boris@kwalus@CanforCorp@DustCount Hello @Kirsty_Gardner_ , thanks for your question! Actually, the material incorporated is barium titanate, which is lead free for human health and environmental reasons. The air flux will first pass through a PM classifier to filter out PM greater that 2.5 um.
