Tesla has filed a US patent utility for a touch-sensitive “pores and skin” that may be molded round robotic fingers and palms, doubtlessly offering humanoid robots with a scalable means of detecting contact, drive and stress.
The appliance, US 2026/0310299 A1, was printed on October 8 and describes a producing course of through which tactile sensors might be printed onto flat, versatile supplies earlier than being heat-formed into three-dimensional shapes.
The submitting was delivered to the eye of Robotics & Automation Information by patent intelligence publication Patentlyze, which has printed an evaluation of the applying.
Tesla’s proposed sensor makes use of two versatile substrate layers carrying conductive areas, separated by a compressible layer. The place conductive areas overlap, they kind particular person sensing factors able to detecting modifications attributable to stress.
The patent describes each capacitive and piezoresistive approaches and lists thermoplastic polyurethane, PET and polyimide among the many attainable substrate supplies.
One of many doubtlessly vital elements of the submitting is its emphasis on manufacturability. Tesla describes processes together with display printing, laser chopping, conductive paste deposition and thermoforming – established manufacturing strategies that would doubtlessly permit tactile surfaces to be produced at scale.
The appliance says: “The 3D tactile sensors can conform to curved geometries and can be utilized for measuring floor drive, contact, and stress.”
Though the submitting doesn’t particularly set up that the know-how will likely be utilized in Tesla’s Optimus humanoid robotic, it identifies robotic fingertips, palms and end-effectors amongst potential purposes.
Tactile sensing is turning into an more and more necessary space of humanoid robotics as builders try to maneuver past fundamental greedy in the direction of extra dexterous manipulation of objects with completely different shapes, weights and supplies.
Patentlyze notes that the submitting doesn’t present figures for the sensor’s sensitivity, decision or sturdiness, that means its sensible efficiency can’t but be assessed.
The patent nonetheless gives one other indication of Tesla’s work on the {hardware} required to offer robots extra refined manipulation capabilities – not merely permitting a robotic hand to know an object, however doubtlessly enabling it to really feel how firmly it’s holding it.
