I met the founder of V1bes, Gustaf Krank, at a wearables gathering in Helsinki last year. He gave a dynamic presentation to the conference and afterward walked me through the technology with a personal demo. The approach is like no other in that is aims to pull together multiple electromagnetic signals from brain, heart and the environment through a ring.
V1bes has launched an idiegogo campaign. I am going to to get one to see how its measurements correlate with Heart Rate Variability (HRV). The idea of electromagnetic “smog” as an influencer of HRV is something worth looking at. Unlike HRV Gustaf’s invention does not have the large number of medical studies with which to compare but that is part of the fun.
