The combination of haptics and olfaction will define a new era of sensory computing—a new paradigm in which users do not just see or hear digital content, but feel and smell it in high-fidelity. Education and therapy will also triumph; e.g., therapy for PTSD can employ controlled scent stimulation to reset memories safely in a virtual environment, and remote classrooms can replicate lab simulations with scent components. Layering of the senses will be the foundation of "digital multisensory twins" across industries.

Breath Diagnostics and Non-Invasive Health Monitoring

Current Trend:

Digital olfaction is rapidly growing in the medical sector, in which it is also gaining momentum for non-invasive medical diagnosis. Breath analysis by electronic noses is capable of detecting disease-associated VOCs that serve as biomarkers for lung cancer, asthma, diabetes, gastrointestinal diseases, and even neurological disorders.
