I. System Architecture
1. Text Description
The system adopts a three-layer architecture: Perception Layer, Control Layer, and Application Layer.
- Perception Layer
- Flexible SBR Fabric Sensor: Embedded in seats or mattresses to collect signals such as posture, body movement, bed exit status, and respiration.
- NTC Temperature Sensors: Arranged at multiple points on the heating pad surface for real‑time temperature monitoring.
- Environmental Sensors (optional): Temperature, humidity, and light sensors for adaptive control.
- Control Layer
- Signal Conditioning Circuit: Amplification, filtering, and analog‑to‑digital conversion.
- Microcontroller Unit (MCU): Runs embedded algorithms to process sensor data, execute PID temperature control, and detect abnormal events.
- Drive Circuit: MOSFET or relays to control the power supply to the graphene heating pad.
- Communication Module: Wi‑Fi / Bluetooth / LoRa / 4G for uploading data to the cloud and receiving remote commands.
- Application Layer
- Cloud IoT Platform: Device management, data storage, and rule engine (e.g., bed‑exit alarm, automatic heating).
- Mobile App / Mini‑Program: Provides real‑time status, push notifications, and remote temperature adjustment for family members or caregivers.
- Institution Management Dashboard: Centralized monitoring for multiple beds, energy consumption statistics, alarm logs, and report export.

II. BOM Cost Estimation (Per System, Based on 1,000‑Unit Mass Production)
Note: Prices are estimated. Actual costs depend on order volume, suppliers, and customization. The flexible SBR sensor and graphene heating pad are patented core components; their unit prices are estimated based on similar flexible electronics.
| Component | Qty | Unit Price (USD) | Subtotal (USD) | Remarks |
|---|---|---|---|---|
| Flexible SBR Fabric Sensor | 1 set | 5.00 | 5.00 | Includes conductive fabric and leads; custom size |
| Flexible Graphene Heating Pad | 1 set | 6.50 | 6.50 | Includes graphene film, insulation layer, leads |
| NTC Temperature Sensors | 2 pcs | 0.20 | 0.40 | Multi‑point sensing for enhanced safety |
| MCU (ESP32 or STM32) | 1 pc | 1.70 | 1.70 | Integrated Wi‑Fi/Bluetooth |
| Power Management (DC‑DC, LDO) | 1 set | 0.85 | 0.85 | 13.5V to 3.3V/5V conversion |
| MOSFET Driver Circuit | 2 channels | 0.30 | 0.60 | For high/low power control |
| Communication Module | optional | 0 | 0 | Included in ESP32 |
| PCB & Connectors | 1 set | 1.15 | 1.15 | Control board and wiring harness |
| Enclosure (Waterproof, Flame‑retardant) | 1 set | 1.45 | 1.45 | Control box and cable protection |
| Others (Resistors, Capacitors, LEDs) | 1 set | 0.70 | 0.70 | Auxiliary components |
| Assembly & Testing | 1 set | 1.45 | 1.45 | Production line assembly, aging test |
| Total | 19.80 | Excluding tax and R&D amortization |
Additional Notes:
- If cloud‑based bed‑exit alarm services are included, add approximately $0.15–0.30 per month per device for SIM data and cloud platform fees.
- For wheelchair or seating applications, smaller sensor/heater sizes may further reduce costs.
- Compared to traditional silver‑paste SBR + copper‑wire heating systems, the BOM cost is roughly 20–30% higher, but the total lifecycle cost is lower due to energy savings and longer service life.
