The current method for leak detect has been tapping on the top of lid and sensing the pressure. This is difficult technique with low accuracy.
Sense side of bottle, push with specific force and determining the movement to determine pressure in bottle. This is primarily in bottles pressurized by nitrogen filled bottles (soda, etc.) where they are more solid. If there is a leak the spring back is greater. The cycle rate is 20 Hz.
Beyond Bottles: This same solution can be used for soft pouch packaging such as contact lenses or coffee “pods.”
Since the SMAC actuator can sense the surface, apply programmable force and monitor position of movement, SMAC has the game changing solution.
This application success story is from SMAC.
