The future development of aromatherapy is inseparable from the support of technology. Through advanced nanotechnology and smart sensors, we can develop a more accurate fragrance release system. For example, using IoT (Internet of Things) technology, consumers can control the intensity and duration of aromatherapy through mobile phone applications, and customize the fragrance according to personal preferences. In addition, combined with AI technology, we can analyze consumers' usage habits, further optimize products, and provide personalized services.
