Hardware and R&D investments are regularly considerably greater than a million dollars. Lots of investors are interested in zero profitability for 12 months (assuming you actually have a business case and a viable product). Outside of the silicon valley software tech bubble, hardware design and manufacture is still an expensive business. I know of a number of companies building machinery for renewable energy generation that have received collectively tens or perhaps hundreds of millions of pounds in funding with no short term profits likely. There's also a lot of medical engineering research going on in universities, which doesn't generally have the same profit requirements attached to it.
However, your concepts sound like vague ideas rather than anything based in reason or science. One dimensional sensing (eg a heartbeat monitor) is fairly easy,but good and reliable multi-variable embedded sensing is hard.
In a later post, you mentioned mapping teeth with a toothbrush. That's not a trivial thing to do - without a fixed frame of reference it would not only be very complex mathematically, but also pretty unreliable. Similarly, chemically analysing anything is not something you can easily do in an embedded and reliable fashion.
A million dollars would not get you very far with embedded, reliable chemical testing. You clearly don't even have a concept of how to do it.
