To start off, let's create a basis for how we will design these! 

First off, we know this is directly meant for VR related things (gloves for example). With this in mind, i'll be making a flex and rotational sensor (will make more sense later). The rotation sensor can use any standard material for now (we also will save working on this for later). However, for the flex sensor, we will use PCBWay as a reference.

From their array of materials, we will select the Nylon HP-PA-12. I used this in the past to make a headstrap for the headset! It also works because at our price point it should be extremely cheap.

Next, we have to think about how everything will actually work for the flex sensor. We will use a linear array of 3x2mm Neodymium Magnets at the base, sitting on a flex PCB ribbon (to still stay connected during extreme bends, while Nylon is flexible, I don't trust it to hold a magnet without popping it). We have a secondary flex PCB with the hall effect sensors above, aimed at the magnets below it. 

Finally, to protect the hall sensor from reading outside forces, we use a flexible ferrite sheet. Ferrite is used within medical equipment and other high magnetic sensitivity equipment where stray magnetic force results in failure. In our case, we are just using it to ensure you can still use your phone while you have the glove on!

To put everything together, i'm imagining there is a singular hard point at the back of the flex sensor with a piece sticking out so you can put some sort of mounting hole through there, then close it with a snap on piece. The flex sensor moves forward and back within a mini rail it slides front and back on! Behind the circular piece should likely be a tiny JST connector, allowing you to send the data to a board of your choice (Which we will design later). 

We will start out with a 2.2 inch strip, separating each sensor/magnet by 0.3 inches but have the first magnet a little further than the rest so we can later do some magic code for when the magnets overlap.
