Feedback helps the controller limit grip force. Listed suppliers offer relevant force-sensing or signal-chain technology, not necessarily this fingertip design.
Where does tactile sensing fit?
The fingertip surface is where a hand meets the object it is grasping. Local contact feedback differs from joint angle feedback and from the combined loads measured at the wrist. These functions can complement one another without being interchangeable.
What kinds of companies appear here?
The mapping includes documented tactile or relevant contact-force capabilities. A company may supply sensing technology or integrate it into a complete hand. The company record identifies the role and whether humanoid use is disclosed or inferred.
What should not be inferred?
An encoder does not become a fingertip touch sensor because it is small enough to fit in a hand. A gripper product does not prove five-finger humanoid-hand supply. Compare the source’s measurement function, location and integration level to the part being studied.
Scope of the company links: Tactile/contact-force sensors and supporting measurement electronics. Joint angle encoders and wrist torque sensors are different from fingertip touch.
Engineering reference: Dexterous finger mechanism. Company-specific evidence is linked from the profiles below.
Humanoid reference designs cover motor drives, BMS, sensing, controllers, and multi-axis hand control. TI supplies chips, not complete mechanical hands.
