Tesla Patent Outlines Curved Tactile Sensors for Optimus Hands

A newly published Tesla patent appears to describe updated hands for Optimus that incorporate soft, curved touch sensors. The concept uses flexible sensing layers and manufacturing techniques that let those layers conform to rounded surfaces, including fingers, thumbs, and palms.

The objective is to give Optimus human-like contact awareness, enabling it to gauge force and pressure that are difficult to capture with rigid or flat sensors.

Flexible Touch Sensor Design

The patent was published and was filed by Tesla on September 11, 2025, claiming priority to a provisional filing from earlier in 2025. Patent drawings depict sensor sections on the thumb, palm, and fingers. Each section can include multiple independently monitored sensing regions, described as pixels, to pinpoint where an object makes contact. With sufficient sensing pixels, the system could potentially infer the type of object based on touch alone, similar to how a human perceives objects.

The filing also describes embedding these sensors within a flexible outer skin for a humanoid robot, and mentions potential use in tools and automated systems.

From Pressure to Electrical Signals

The sensor stack resembles a layered sandwich: two flexible sheets carry conductive patterns, separated by a deformable layer. Overlapping conductive areas define individual sensing locations.

Tesla details both capacitive and resistive implementations. In the capacitive version, applied pressure compresses an insulating separator, bringing conductive regions closer and changing capacitance—the ability to store electrical charge—which connected electronics can measure. In the resistive version, the middle layer uses a material whose electrical resistance changes when squeezed, allowing electronics to detect contact or pressure.

Manufacturing Curved Sensors

One approach starts with flat stock: conductive ink is screen-printed onto flexible sheets, which are then heated and formed over a mold. After cooling, the stacked layers retain their curved shape.

The second approach molds the base first, then adds conductive patterns directly to the curved surface. Options include dispensing conductive ink with a positioning system, transferring ink with a flexible printing pad, or using a laser to prepare selected areas for metal plating.

Practical Applications and Optimus Context

In use, contact signals from multiple parts of the hand could help a robot modulate its grip, apply appropriate pressure to the object it is handling, and potentially identify an object by the shape it feels. Curved tactile coverage also simplifies integration into robot hardware and enables far more pressure-sensing locations.

Although the application does not explicitly name Optimus, Tesla has been developing the third gen version of Optimus, and Elon Musk has highlighted progress on its hands. Tesla has said it will not show Optimus Gen 3 until it is close to production to prevent being copied.
