A few years ago, I worked for a small startup looking to use wearable devices to detect early changes in gait as a means to effectively deliver early intervention techniques. The science around the topic is solid - there is good research backing which parameters of gait are most predictive and what therapies are most effective for any given scenario.
The problem we always encountered was compliance. Customers (senior living facilities, insurance agencies, etc) want to know that the devices are being used. Seniors are notoriously slow to adopt tech, and adding another device to daily life is the last thing most seniors that we spoke to wanted to deal with.
We got to interview with YC for this idea but were rejected. Skimming the companies from that batch I later found https://www.totemic.com/ They use back-skatter technologies to provide a compliance-free fall monitoring system. After spending two years in the problem space, I knew a superior solution when I saw it.
