The PulsePoint ScentSig is a subdermal biochemical scent synthesis implant that replaces and augments the body's natural scent signature through a network of small nodes positioned at high-warmth pulse points — behind the ears, at the inner wrists, and optionally along the neck and collarbone. Each node contains a programmable micro-dispensary loaded with a library of synthetic aromatic compounds, blended and released in response to body temperature, sweat output, and user-defined schedules. The system does not simply mask natural body odor; it synthesizes a completely custom personal scent that interacts with the wearer's natural skin chemistry to produce a unique, skin-specific result — the same preset will smell slightly different on every person who runs it. Users can choose from PulsePoint's library of over four thousand base profiles, work with a scent designer to create a bespoke signature, or use the companion app's AI blending tool to build something personal. Scent intensity scales automatically with physical activity and ambient temperature. The system can also include optional sub-threshold pheromone compounds — not mind-altering, but contributing to the general impression of warmth, trustworthiness, or vitality depending on the profile selected.

The ScentSig is one of those implants that people who have it cannot imagine living without, and people who do not have it are sometimes mildly skeptical of. In daily life, it means never thinking about deodorant again, never worrying about stress sweat in a meeting, never smelling like whatever you ate for lunch. It also means your scent is entirely yours — designed, intentional, consistent. In a city as sensory-dense as GLMZ, where transit cars and open markets press strangers together constantly, the ability to control your olfactory presence is quietly significant. The product has strong uptake across all tiers: Shelf residents get the basic two-node version at pharmacy kiosks; Tier 4 professionals commission bespoke scent signatures the way their grandparents commissioned tailored clothes. The optional pheromone layer is technically unrestricted but generates ongoing low-level ethical debate that PulsePoint's legal team monitors carefully.
