  • These are nice little devices but there are a few issues with them - they can "sense" force but they cannot "measure" force in any conventional way - you would need to calibrate the device regularly to make any kind of valid measurement because they drift with usage and the environment.

    Basically it's a metal film pressing on a carbon pad - not dissimilar to the old carbon microphones - and a common problem is that the metal film will develop cracks if you bend the device too much or too often. They are great for experimental use, project use, demonstration etc - anything that requires the sensing of pressure but not measurement - keep them flat and don't bend them and you'll be fine.

No public wish lists :(
