A prof of mine back in Oxford told us a story how he invented a similar noninvasive blood glucose monitoring technique, shown to work, patented it, patent bought by big pharma and silenced.

I'm more than convinced we had this tech ages ago but it was not profitable to deploy it. Now either relevant patents are finally expiring or the market has changed enough to allow such players to enter.

Do you have a link to his patent? You should be able to find it by his name.

But the hurdle today isn't in the physical sensing technology, it's how to detect an accurate signal from extremely noisy data.

Patents aren't the main blocker -- nobody has built this at all in a way that is accurate enough. And Apple has been trying hard, and they have nothing to do with Big Pharma.

I'm sceptical of this story. This is a huge market and it was a huge market 20 years ago.

I participated in studies with prototype devices to measure blood glucose and nobody I talked to mentioned patent blocks.
