Licking this “lollipop” will let you taste virtual flavors

Scientists in Hong Kong have developed a lollipop-shaped device that can recreate different flavors in virtual reality. This breakthrough in taste simulation uses a method called iontophoresis, which transports flavor chemicals through safe hydrogels using ion flow. The device offers advantages over other taste simulation methods, including safety, low power use, and precise flavor control. This innovation could potentially enhance immersive experiences in virtual and mixed-reality environments by adding taste sensations to existing visual and auditory elements.
