SCENTIENT
A multisensory device that connects scent, sound, and memory.
SCENTIENT – Overview
SCENTIENT is an experimental interface that transforms data into scent, creating a new way of perceiving information through olfaction. The device explores multi-sensory interaction by translating sound waves or user inputs into corresponding fragrance outputs. This project pushes the boundaries of conventional user interfaces by introducing smell as a medium for ambient feedback, mood influence, or sensory storytelling.
Challenges
One of the key challenges was mapping abstract data to physical scent responses in a way that felt meaningful and consistent. Engineering a compact, reliable scent diffusion system was also technically demanding, particularly when working with heat-sensitive components and limited space. Balancing the artistic concept with functional hardware and ensuring the experience remained intuitive were crucial hurdles during development.
From Concept to Prototype
SCENTIENT began as a speculative exploration into how scent could be used as a data interface. The early phase focused on translating abstract sensory experiences into tangible outputs—specifically, turning sounds and user-triggered events into smell. Initial sketches and research evolved into CAD models and physical prototypes using 3D-printed enclosures, microcontrollers, and scent cartridges. Iterative testing helped refine the scent delivery system, ensuring it was compact, safe, and responsive. The final prototype demonstrated a working proof of concept: a device that emits different scents based on live or stored data inputs.
The SCENTIENT App
To accompany the physical device, a custom app was developed to control and personalize the experience. The app allows users to select triggers (e.g., music genre, voice tone, ambient noise) and assign them to specific scent profiles. It includes a clean, intuitive UI for managing scent intensity, duration, and presets. The app also tracks scent history and usage patterns, offering potential for biofeedback, meditation, or ambient mood enhancement. The digital interface was designed to feel as tactile and expressive as the physical device, bridging technology and sensory design.
