One of the biggest hurdles in any type of medical product is the regulations required to build and sell it (at least here in the USA). I have worked on a couple of medical products and the FDA requirements were so overwhelming. Having said that, I agree with the need for a strongly regulated procedure for bring medical products to the market.
There are many compelling medical products that could help to improve lives, so don't ever stop thinking about what might be. Just be ready to do a lot of work.
That's a good idea, we will study the technology continuously.
You're right, the reaction has been very positive! Vital and Lenovo announced the Vital Medical Mod last week at CES - https://blog.motorola.com/2018/01/09/new-year-new-moto-mods-and-a-challenge-for-more/
I believe there Medical Mods would be very well received by many people that have various medical conditions that require monitoring and periodic tests. Here are some examples: blood pressure mod that connects to a wrist or arm cuff, diabetes, electrocardiogram, Holter monitor, even urine test. Also other mods can add the functionality of strong microphone to hear and record the baby in the womb heart beat during pregnancy and other can add the functions of audio/video baby monitor. Any ideas on the subject ?
