Utilize haptics to quietly send information to the user

Similar projects worth following
The haptics can send a variety of differentiable effects to let the user know when they need to leave for an appointment or are receiving a call from a specific person, etc.

Design is simply velcroed flexible PCB that has our curved battery, 3dB BLE Flex Module, Qi/USB Charger Flex Module, and the LRA Haptic Flex Module and a 9mm Samsung LRA. We might include the 12axis to provide a notice recognition gesture/movement. Waiting on a solid Qi/USB Charger Flex Module.

    This design is pretty easy to design. We are using the Seggar J-link, but still having problems including the BLE stack. I'll be working on this soon.

    In our initial layout, we chose to hot glue the motor on to the board. I do not believe it will be durable, but we will experiment with epoxies later.

    The circuit board may be glued or sewn to fabric. We recommend gluing at this point so that the board is on a more comfortable cloth around the skin. So any strap with velcro should work out.

    While we are waiting on the charger flex module, we made a design using a simple watch battery. It is not perfect, but it is simple enough. Instead of the Qi/USB Charger Flex Module and a curved Li Poly, we used a CR2450 battery holder.
