**GlowTact: Simple and Compact Vision-Based Tactile Sensing with High Sensitivity and Spatial Resolution**

GlowTact用压响应视觉机制直接呈现接触压力，在触觉传感实验中验证高灵敏度与丰富空间细节。

## 核心要点

- 现有VBTS设计难以简化并适配人形机器人指尖的尺寸与约束。
- GlowTact仅需单色非定向照明，原始触觉图像直接表示压力分布。
- 该原理支持紧凑可定制传感器，无需显式几何重建仍保留空间细节。
- 实验展示克级接触检测、准确法向力估计及M1螺纹等精细几何重建。

**验证范围与局限**：验证范围为触觉传感能力展示，包括克级接触、法向力估计和精细接触几何重建。

## 英文摘要 (Abstract)

Vision-based tactile sensors (VBTS) provide rich contact information for robotic manipulation, but existing designs can be hard to simplify and adapt to the size and constraints of humanoid fingertips. We introduce \textbf{GlowTact}, a pressure-responsive vision-based tactile sensing mechanism that directly visualizes contact pressure. \textbf{GlowTact} requires only single-color, non-directional illumination, and the raw tactile image directly represents the pressure distribution without explicit geometry reconstruction. This simple sensing principle enables compact, customizable tactile sensors while preserving high sensitivity and rich spatial detail. We demonstrate gram-scale contact detection, accurate normal-force estimation, and reconstruction of fine contact geometry, including M1 screw threads. These results establish \textbf{GlowTact} as a practical new sensing technology for compact humanoid fingertips, combining a durable nitrile membrane and simple optical design with sensitive and information-rich tactile perception.
