Yimu Tech launches sub-3mm optical tactile sensor SENTRA T0
KEY FACTS
- Yimu Tech has launched SENTRA T0, an optical bionic tactile sensor that is less than 3 millimeters thick.
- The company calls it the world's thinnest mass-producible bionic visual-tactile sensor.
- Founder Li Zhiqiang said the company's technology foundation is built around optical chips.
- Li Zhiqiang believes the biggest bottleneck for embodied intelligence is insufficient data from the physical world.
- The company chose the optical tactile route, using light to detect deformation rather than taking photos directly.

PHYSIX OBSERVATION
Tactile sensing is the key shortcoming keeping robots from moving beyond demonstrations to real work. Yimu uses optical chips to digitize deformation, and its 3-millimeter thickness solves the problem of not fitting inside dexterous hands. But the real test lies in mass-production consistency and data accumulation. Whether optical touch can become a mainstream route still depends on validation in scenarios such as automotive final assembly.
