While building, testing, and experimenting with the new HSMS-2820-TR1G full bridge rectifier today, I observed a consistent AC voltage increase when touching one specific part of the circuit. I injected 1 VDC into the DC output side of the bridge. The voltmeter was set to VAC, with the black lead on the negative DC output and the red lead on one of the AC input terminals. Only this measurement point showed a voltage change when touched.

This appears to be due to capacitive coupling from the body, allowing ambient AC fields to influence the circuit. The system responds noticeably to human contact at that node, further confirming the AEFC’s sensitivity to field-based interactions and environmental input.

Although this HSMS-2820-TR1G bridge has not yet been integrated into the main AEFC system, this test represents a standalone experimental setup designed to explore its behavior independently. While the same ambient energy principles apply, this configuration is its own isolated test circuit and should be understood as such.

Notably, the voltage response to touch only became clear and consistent after applying a DC input of approximately 1 V. Below this threshold, the effect was negligible. This suggests the system requires a minimum energizing voltage to enable strong capacitive coupling from the human body and ambient AC fields.

A video showing the effect has been added to the project files section as Touch.mp4. This bridge will be integrated into the AEFC once testing is complete.
