Building and testing a new wearable device
In the previous posts, we explained our project, as well as the technical and scientific foundations for it. We also pointed out that a thermal energy transfer sensor embedded in a wearable device is not enough. It is far from enough. We need to crunch the data into something that makes sense. And for that purpose, we need an algorithm.
It’s all about the algorithm
An algorithm is a finite sequence of well-defined, computer-implementable instructions, typically to solve a class of problems or to perform a computation. In our case, the algorithm is based on artificial intelligence models that learn from the incoming sensor data. The more data we feed in the more accurate the result will be – a result which will help people improving their sports performance.
This takes a lot of work, data, and physiological trials, indeed. But in the end, we have a mathematical system that analyzes the sensor data in real-time and, from this, calculates the core-body temperature.
What does it take?
Physiological trials are the best way to assess the performance of the thermal energy transfer sensor: we learn how the system works on a real body, and develop an algorithm that will be accurate and responsive under live conditions. Briefly said, we are adjusting the whole wearable under controlled conditions before being able to run more advanced tests.
Physiological trials take time and resources. At CORE, we are following a clear method:
- Choosing the right volunteers for the testing. As the algorithm should work under every condition, we have created a testing matrix to cover as many situations as we can. This will be the best proof-of-work for our device.
- We want also to figure out the best way to make the sensor work on the human body. Because of this, during the testing, volunteers are wearing both a body patch and a smartwatch with our sensor embedded.
- The data taken need to be compared with a reference system that we know is accurate and reliable. In our case, all the testing volunteers also ingest an electronic pill that tracks the core body temperature in real-time.
- We are gathering information before, during, and after physical exercise. Volunteers work out for 1+ hours indoors. After a shower, we reattach the sensors and track the cool-down process.
We are currently in the alpha phase of testing. We plan to perform numerous tests with different volunteers, fulfilling the requirements specified in our matrix. If you want to help us, fill out the form below and become a volunteer!
Finally, during this testing, we are not only working on the algorithm. We are also working with people regarding the desired features of the device, as well as its pricing. Remember, this is a project with a strong focus in the sports community. Do you want to participate in the project? Drop us a line and let’s start building a new generation of wearables!
