Cardiovascular Wearable
I've been blogging about learning embedded C, while building a wearable device for cardiovascular research. I'm trying to improve access to raw data, expand the sensing modalities, and improve data quality for studies in to diseases that can present through cardiovascular mechanisms. If you’ve done research with wearables, I’d be interested to hear what the biggest limitations were for you, as well as any general advice! I used to be a biomedical postdoc, then medical device engineer, it was so difficult to do wearable research at scale unless you were inside one of the big companies, you could buy the devices, but getting to the raw data was often impossible, and there were always data dropout issues over longitudinal studies. I suspect it's partly because the hardware and systems are designed primarily for low cost consumer applications rather than open ended research, whilst companies also see the longitudinal data sets as very valuable and are reluctant to make them fully accessible. So I'm trying to build something more research focused. I've been writing about the embedded C side of the project as I go: https://skoopsy.dev
