The Dermal Emission Suppressor is a full-body compression underlayer embedded with a dense mesh of bioelectric regulation nodes developed from Zheng-Dao's research into autonomic system intervention. The underlayer interfaces non-invasively with the wearer's skin surface, monitoring galvanic response, localized surface temperature, and sweat gland activity across the body in real time. Using this data, the nodes apply targeted micro-current stimulation and localized thermoelectric cooling to suppress the involuntary physiological signals that thermal imaging, biometric stress sensors, and galvanic scan systems rely upon to detect and profile human presence.

The Suppressor's primary function is thermal: it maintains the wearer's skin surface temperature within 0.3 degrees of ambient environment temperature by dynamically redistributing body heat through a network of thermoelectric channels that terminate at a heat-sink collar worn at the back of the neck. This collar expels accumulated heat as a diffuse low-temperature plume rather than a concentrated body-shaped signature, dramatically reducing the wearer's profile on thermal imaging systems. A secondary function targets galvanic and stress-response suppression — the bioelectric nodes modulate skin conductivity to flatten the stress-response spikes that biometric scanners at corporate checkpoints use to flag persons of interest regardless of their visual identity.

Zheng-Dao markets a civilian variant of the underlying thermoelectric technology as a medical garment for patients with autonomic dysregulation disorders, which provides a plausible cover story for possession. The full Suppressor, however, exceeds medical specifications significantly and requires calibration to the wearer's specific bioelectric baseline — a process that takes approximately two hours and leaves a calibration record in Zheng-Dao's service network that cautious buyers pay considerable sums to have expunged.
