Scientists at China's City University of Hong Kong and Beihang University have created a wireless olfactory feedback system that incorporates smells into virtual and augmented reality via miniaturized odor generators (OGs).
The system heats and melts odor-infused paraffin wax on OGs to induce phase changes and release different scents with adjustable concentrations.
The researchers engineered a skin-integrated dual-OG array that can be mounted on the upper lip to deliver odors rapidly.
They also designed a flexible facemask with nine OGs that can dispense hundreds of blended odors.
Volunteers were able to identify the OG-generated smells with 93% average accuracy.
