Mounting Sensors on Bear

Here is the Design I have thought of to mount the sensors on the bear's body in stead of putting them inside. The bare's jacket can be made of plastic to protect water, moisture and other environmental disturbances.

by this way, the shape and features of the toy can be more flexible and it only requires to wear the touch sensor jacket to sence and transfer the hug.



This is the sensor map to place on the toy's jacket. Depending on the size of the toy, the unit of sensors can be increased or decreased.
For this example bear, the sensors can be added as: 4 on front, 4 on back, 2 for each sides and 2 for each arm.
The wires from the sensors can be attached to the circuit from the back side of the jacket and the circuit box may be embedded inside the toy.
