Tesla has applied for a US patent on soft, curved touch sensors for robot hands. The drawings show a robot hand with one sensor along the thumb, one covering most of the palm, and one on the index finger. The application was published on October 8, 2026.
The filing describes the sensor as a tactile "skin" for a humanoid robot. It does not name Optimus.
How the sensor works
- Layers. Two layers of flexible polymer carry conductive regions. A separator layer sits between them.
- Two kinds. With a dielectric separator it is a capacitive sensor; with a piezoresistive one it is a resistive sensor. Pressure squeezes the separator, and the electronics read the change in capacitance or resistance.
- Pixels. Each sensor can have any number of "pixels" that detect contact independently.
- Protection. Protective layers, such as foam, can go on top to shield the sensor from the environment, wear and impacts.
Two ways to make it
| Method | Steps |
|---|---|
| Shape after building | Build the flat layer stack, then heat-shape it (thermoforming) to the shape of a finger, palm or gripper |
| Shape first | Shape the base layer first, then add the conductive traces and separator on the curved surface |
The conductive traces can be made by screen printing, laser-direct structuring, pad printing, conductive paste, or 3D dispensing.
This is a patent application, not a granted patent.
