One of the most difficult tasks for wearable gadgets is to strike a balance between battery life and functionality. Heart rate monitoring is one of the core functions of the product, which consumes a lot of energy. However, we couldn't simply reduce the frequency of measurement because it increases the risk to the user. For emergency physicians, every second counts.
The device must gather reliable data about the user’s health (HR, HRV, SpO2) and transmit it through GPS or Wi-Fi. If taking the most harmless instances, erroneous data will result in a real worry for relatives, while in the worst case scenario, ambulance doctors might even respond to a fake call. The prospect of endangering the user's life was highly inappropriate.
As a wearable device development company, EnCata had a hurdle in implementing efficient ergonomics, portability, and functional needs all in one device. The entire electronic component must fit into a small package and operate properly. The difficulty of transferring the gathered data to a recipient was first and primarily posed by the compact arrangement.
We had to develop all the technical systems of the product and get an MVP, which the startup could then hand over to real users for testing. It’s essential to bear in mind that the startup had a limited budget to achieve such an ambitious goal.
