Wearable medical smartwatch

The smartwatch Sputnik checks a person’s vital signs and calls an ambulance if their health is deteriorating. It has the ability to save the life of someone recovering from heart attack or stroke, especially when there is a high risk of recurrence.The bracelet will also provide timely aid to an elderly person, notifying doctors and relatives of their falling health.

Challenge

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.

Approach & Solution

We selected a serial enclosure based on the industrial design we had established in order to design the MVP faster while still staying inside the customer's budget. This enabled us to cut down on mechanics development costs. The enclosure was then modified by our engineers, Our designers created the product stickers. The MVP's use of a conventional enclosure also allowed for no fabrication costs. There was no need to paint or polish the enclosure. Besides, we machined the correct slots and holes with no extra tooling or rapid prototyping processes.

We went through multiple iterations when developing the electronics . The conclusion we came to was that proper antenna placement inside the enclosure is important for ensuring reliable communication, as all elements must not interfere with each other and lower communication quality.

3D CAD model of the Printed Circuit Board

The proprietary algorithm for processing sensor data and translating it to HR, HRV, and SpO2 allows you to maximize the capabilities of the selected sensors while also reducing the device's battery consumption.

Based on the Customer's ideas, we have built our own algorithm for obtaining, processing and analyzing "raw" data, which allows for reliable data monitoring of HR, HRV, and SpO2.
