Juqiao Tactile Glove Specifications
Full technical specifications for the Juqiao Precision Textile Electronic Skin (高频版 / High-Frequency Version), sensor array, acquisition module, and serial output format.
Verify against product documentation.
Some values below (pressure range, exact node count, environmental ratings) are based on the V2.3 and bilingual V1.0 spec sheets and the sensor class. Always cross-reference with the official spec document before finalizing a hardware design. Contact Juqiao Precision at jq-industries.com or info@jq-industries.com for the latest revision.
Sensor — Textile Electronic Skin (High-Frequency Version)
| Vendor | 矩侨精密 (Juqiao Precision / JQ Precision) |
| Product name (CN) | 织物电子皮肤（高频版） |
| Product name (EN) | Textile Electronic Skin — High-Frequency Version |
| Spec version | V2.3 (CN); V1.0 CN-EN bilingual |
| Sensing technology | Woven conductive fiber — piezoresistive textile matrix |
| Form factor | Flexible textile glove or conformal sensing sheet |
| Sensing coverage | Full hand: palm, finger pads, and fingertips (glove variant) |
| Sensing nodes | 64 (multi-point array; confirm total count and layout from spec doc) |
| Measurement type | Normal pressure (contact force distribution); no shear or torque components |
| Pressure range | 0 – 200 kPa |
| ADC resolution | 16-bit per sensing node |
| Full-scale ADC value | 0xFFFF ≈ 200 kPa (confirm from calibration sheet) |
| Sampling rate | Up to 200 Hz full-array (high-frequency version) |
| Response time | < 10 ms (typical) |
| Latency (sensor to USB) | < 5 ms at 200 Hz |
Physical & Environmental
| Minimum bend radius | < 0.1 mm — folds freely without recalibration |
| Durability | Automotive-grade impact tested; maintains elasticity and rebound after repeated deformation |
| Breathability | Yes — standard textile breathability retained |
| EMI resistance | High — fiber construction inherently isolates electromagnetic interference |
| Operating temperature | 0 – 60 °C (typical) |
| Connector | FPC ribbon cable to acquisition module |
Acquisition Module
| Host interface | USB 2.0 full-speed — presents as CDC ACM serial device |
| Serial baud rate | 921600 bps (default; configurable via configuration tool) |
| OS support (Linux/macOS) | No driver required — CDC ACM driver built into kernel |
| OS support (Windows) | CP210x or CH340 driver (included); Windows 10/11 |
| Power source | Bus-powered via USB (5 V, < 500 mA) |
| Configuration tool | Windows x64 GUI — sets sample rate, channel mask, calibration offsets |
| Linux/macOS config | Software commands via serial protocol (V2.3 protocol document) |
Serial Frame Output Format
| Field | Size | Description |
|---|---|---|
| 0xAA 0x55 | 2 bytes | Start delimiter — sync bytes for frame alignment |
| N | 1 byte | Channel count — number of active sensing nodes in this frame |
| pressures[0..N-1] | N × 2 bytes | Big-endian unsigned 16-bit pressure value per sensing node; 0x0000 = no pressure, 0xFFFF ≈ 200 kPa |
| CRC16 | 2 bytes | CRC16 checksum over the channel count and pressure array; validate in production code |
Total frame length = 5 + 2N bytes. At N = 64 channels, each frame is 133 bytes. At 200 Hz, the sustained data rate is approximately 213 KB/s — well within USB 2.0 full-speed capacity.
Platform Telemetry Format (Fearless Platform)
| Protocol | WebSocket — JSONL frames |
| Endpoint | /api/teleop/ws |
| Registration field: device_type | "juqiao_textile_skin" |
| Registration field: capabilities | ["tactile", "pressure_array", "telemetry"] |
| Telemetry field: pressures | Flat array of N unsigned 16-bit integers (one per channel) |
| Telemetry field: ts | Unix millisecond timestamp (integer) |
| Bimanual member IDs | "juqiao-glove-right" / "juqiao-glove-left" |
| Session creation endpoint | POST /api/teleop/sessions/create-sdk |
| GloveWorkbench visualization | 2D pressure heatmap using channel-to-node position layout from spec document |
Comparison with Paxini GEN3 (Rigid Tactile Tile)
| Sensor substrate | Textile (Juqiao) vs. rigid tile (Paxini) — fabric conforms; tile is fixed geometry |
| Measurement type | Normal pressure distribution (Juqiao) vs. 6-axis force/torque per tile (Paxini) |
| Coverage area | Whole hand in one continuous surface (Juqiao) vs. discrete tile placement (Paxini) |
| Best for | Contact area, pressure map, slip detection across large conformable surface (Juqiao) vs. per-fingertip force decomposition (Paxini) |
| Interface | USB CDC serial (Juqiao) vs. USB / SPI (Paxini GEN3) |
