Abstract
Body channel communication (BCC) is a most power efficient way for communications among sensors in a wireless body-area network (WBAN). In BCC, the forward signal of the quasi-static field is conducted by the body surface, whereas the backward path is formed by the electrostatic coupling between the GND electrodes (GEs) of transmitter and receiver. As a result, the transmission loss is dominated by the backward path, which has high impedance due to small air capacitance between two compact GEs. Conventional backward path enhancement techniques make use of a large inductor to resonate with the air capacitance in order to reduce the impedance. Such approach is not suitable for integrated solution and not reconfigurable for varying communication distances. In this paper, we propose a novel active channel enhancer to compensate the loss in backward path, which is integratable and reconfigurable for variable distances and frequencies. Designed with 0.13 µm CMOS process, the proposed active enhancer improves the quasi-static coupling by more than 15 dB for a wide frequency band of 40 MHz–120 MHz compared to the 4 dB enhancement of conventional method; and the power consumption is only 0.6 mW.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
