I had some savings during the pandemic and I needed to choose between down payment for a house or fund my patient monitoring venture. I had contact with few care home chains and very positive feedback and even agreement for a test run. I was pussy and went for a home. Couple years later no semiconductor parts were available anymore and I was super happy with my cautious decision. I heard of few hardware ventures, which died during part shortage. What an unfortunate time. There was a product, market opportunity, but simply no production material.

The original sensor got discontinued, I have some savings again and would love to try the same with radar approach. Anyone willing to analyze well being of old people from radar data together?
