Development of a Piezoelectric-Based Odor Reproduction System

Abstract

Odor reproduction, a branch of machine olfaction, is a technology through which a machine represents various odors by blending several odor sources in different proportions and releases them. In this paper, an odor reproduction system is proposed. The system includes an atomization-based odor dispenser using 16 micro-porous piezoelectric transducers. The authors propose the use of an electronic nose combined with a Principal Component Analysis–Linear Discriminant Analysis (PCA–LDA) model to evaluate the effectiveness of the system. The results indicate that the model can be used to evaluate the system.

An experimental paradigm for studying EEG correlates of olfactory discrimination

“…Yet, the settings proposed here are more natural, comfortable and controlled compared to both manual delivery of odors ( Saha et al, 2013 ; Aydemir, 2017 ; Abbasi et al, 2019 ; Zhang et al, 2021 ; Ezzatdoost et al, 2020 ) and using an olfactometer attached to the nostrils ( Murphy et al, 2000 ; Rombaux et al, 2006 ; Invitto and Mazzatenta, 2019 ). While the field has been growing of olfactory displays that achieve the stable perception of odors in a naturalistic setup ( Nakamoto et al, 2012 ; Wen et al, 2018 , 2019 ), only a few EEG studies employed such displays. Amores et al (2018) conducted a study with a wearable olfactory display (an olfactory necklace) and recorded EEG data with a low-cost EEG headband.…”

The Development of a Simple Projection-Based, Portable Olfactory Display Device

“…These can be divided into two types: ubiquitous or wearable [8]. Ubiquitous type products function by releasing the scent into a closed area where the user (or users) are located, via methods such as an electrical fan [9], piezoelectric [10] or a heater [11]. This type of device is similar to a digital scent diffuser.…”
