So you embed magnetic particles in silicon rubber and magnetize them, then use magnometers to detect how the magnetic field is changing from a few different points of reference in order to detect the deformation of the rubber and from that you can analyze the "pressure points" on the surface. the innovation here is that you dont have a lengthy re-calibration of your "input signal" to the particular magnet-infused silicone interface because the manufacturing makes them consistent enough to be replaceable parts?

this makes advanced touch sensors more like machine-cut screws than bespoke hand-forged nails.

I'll bet you could open the grippers fully and recalibrate on power up.

Great idea, you could do the same with a capacitive xy sensor.

Exactly! You need little to no re-calibration.

With capacitative sensors, it is unclear from existing literature if it is possible to detect shear. Additionally, they generally operate at significantly lower frequencies.
