The use of phone to check if you are sick or not has just begun, one example of this is that Apple recently released its new ios that contains the app “Health” where you can check how many steps you have taken on a day, check your pulse rate or how many calories you have burnt during the day.
We simply want to check our health at home with ease so we don’t have to go to the hospital, this requires that our product has to be small and cellpowered and of course cheap.
This report describes our examwork where we investigate if we can build a blood flow measurement/measuring prototype, it has to be cheap, cellpowered, small and it must have theability to send its information via the protocol NFC.
We were given a Raspberry Pi, this to keep the price down, and for the NFCsending issue wehad to use Androidphones/tablets with NFC on them. To reach the goal we had to program the Raspberry Pi in C to take care of the information, and make an app for Android in Java that reads the information wirelessly and can show the information on display.
Late in the project we noticed that our ADC couldn’t handle the probe, wich made us unable to realise the blood flow probe measurements. Therefore our finished product is not the complete product we were hiping for.
We had to change the probe to a IRdistance sensor, wich we chose because then we would still be able to show that we can send information from a sensor via ADC to Raspberry Pi and then to the phone/tablet.
Our finished product became a small, cheap and cellpowered distance measurer. This showed us that we have the knowledge to make a small, cheap and cellpowered hospital gear.
In the future there are big possibilites with what you can do with this technique for example, check for disease, blood flow, lung capacity just by reading via moving your phone over for example a watch.
