Introduces shark-derived ampullae of Lorenzini — specialized electroreceptor organs — along the jawline, temples, and forearms. The user gains the ability to detect bioelectric fields generated by living organisms and active electronics within a 3–5 meter range. The sensation is described as a 'pressure' or 'tickle' that varies with the strength and frequency of the field. Living bodies produce distinct signatures; electronic devices produce others. A skilled user can detect a person hiding behind a wall by their bioelectric field, identify the type of electronics someone is carrying, and sense the presence of active surveillance equipment. Gravemoss Biofoundry developed the modification for security applications, but it has found a wider market among the paranoid, the curious, and the professionally cautious.
