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.

From “Lifelike” to “Alive”
Bionic Skin Is More Than a Shell
For service robots, humanoid robots, and high‑end animatronics, realism is no longer just about appearance. True human‑like interaction requires skin that delivers warmth, tactile sensitivity, and dynamic response.
With the in-depth iteration of Internet of Things (IoT) technology, Bluetooth, as the core carrier of short-range wireless communication, is ushering in a technological revolution represented by Bluetooth 6.0/6.2. Compared with previous protocols, Bluetooth 6.0/6.2 achieves breakthroughs in Channel Sounding (CS), ultra-low latency and security protection. Coupled with the audio experience upgrade of LE Audio (Low Energy Audio) and the networking expansion of BLE Mesh, it has become the core technical standard for consumer electronics, smart mobility, smart home and healthcare in 2026.
This paper focuses on three mainstream scenarios: Automotive, Smart Home, and Wearable & Medical Healthcare. It dissects complete application solutions, technical details, typical architectures and deployment effects, with precise chip/module selections and brand models, providing a full-dimensional reference for industry R&D, selection and mass production.
I. Existing Technology:
Traditional copper wire heating pads have inherent issues that are difficult to solve:
Due to metal fatigue characteristics, when the heating pad is subjected to prolonged stress, it is prone to metal fatigue, leading to increased resistance in the heating wire until eventual failure.
