The bracelet will have sensors that will measure the heartbeat, the tension and other types of measurements. These values will be sent to the app in the device by Bluetooth. Once the data is saved in the app, thanks to an algorithm the type of nutrients needed will be provided and different recipes and foods will be suggested.
Therefore, the design tasks are:
- Establish a good material for the bracelet that allows the installation of the sensors
- Select the right sensors so the reading is accurate
- Establish a good Bluetooth connection so the data is transferred in the minimum time possible
Design goals and specifications
- Safety: The material of the bracelet cannot be toxic even if we mix it with fluids and since the bracelet needs to be worn every day all day it has to be soft and comfortable
- Environmental Protection: The Bluetooth connection won't be on all the time the sensors are working, only for specific hours. Instead, the bracelet will also count with a memory where all the data will be stored until the information is transferred to the device
- Reliability: The bracelet needs to be tested in all type of conditions since it is going to be used in different weathers and in different situations
- Performance: The performance, which is described above, needs to be as immediate as possible
- Ease of operation or operating conditions: The bracelet needs to be designed to work differently depending on the type of person who is wearing it. Some of the things to look at will be the weight, age , height, allergies, illnesses or lifestyle
- Durability: The material of the bracelet as well as the sensors needs to be resistant with a long life
One of the paths discarded is to exchange the sensors for another type of device for measurement such as stethoscope. This path will have as final product a bracelet uncomfortable since people would fell wearing the bracelet all the time. Also, it would be very uncomfortable for kids.
