抄録
The sustainability of wearable sensing devices requires low-power operation. This study presents a battery-free wireless electroencephalography (EEG) transmission system powered solely by energy harvested via a thermoelectric generator. The system integrates compressed sensing (CS) with random undersampling and a waveform-similarity-based reconstruction basis, achieving a high compression ratio (CR) while preserving reconstruction accuracy. An outdoor demonstration at the Expo 2025 site in Osaka, Kansai, Japan confirmed stable on-device operation, including EEG digitization, compression, and wireless transmission, powered by the temperature difference between the body and the ambient air, with the ambient air temperature at 32.5–32.8°C, without forced airflow or external power. Using 100 segments from the CHB-MIT dataset (chb14), the proposed system was evaluated using a single fixed measurement matrix under the ambient temperature during the demonstration, yielding an average normalized mean square error of 0.047 with CR = 6. These results demonstrate the potential of CS as a next-generation battery-free biosensing platform.
