Can we trust in devices built by John Mellvine & Hugo Plácido da Silva, such as the Vernier Go Direct Respiration Belt & the Inductive Respiration (RIP) Sensor from BIOSIGNALS & the Respiration (PZT & RIP) Analysis Add-on? – PETER GAMMA (Director & Physiologist), MEDITATION RESEARCH INSTITUTE SWITZERLAND (MRIS)

The Vernier Go Direct Respiration belt:

continues to monitor respiration for 30 min. after we have removed if from our chest.
Is there someone else who does reseach with this device than John Mellvine PhD?

And we have the alternative Inductive Respiration (RIP) Sensor from BIOSIGNALS:

-Which only has been used in a converence paper:

-Which eventually is a paid promotional paper.

Are these devices more than demos?
Peter Gamma from www.petergamma.org supposes not. And that these sellers can sell their demo products to Peter Gamma from www.petergamma.org is only a demo as well.
Since what John Mellvine and Hugo Plácido da Silva has built Peter Gamma can also be built by himself.
And building himself is more attractive for him.
But he has first to go to the scientific literature here:

From where John Mellvine and Hugo Plácido da Silva most probably found the instructions to build their devcies.
But Peter Gamma from www.petergamma.org would like to thank John Mellvine and Hugo Plácido da Silva for their demo devices, which he can adapt for his own needs.
