Thanks to the National University of Singapore, you will soon be able to taste the food that is put before your eyes when watching your favourite cooking programs. The university has developed a new technology that can electronically recreate taste buds.
The simulator uses electrodes to stimulate taste buds to reproduce salt, sweet, sour and bitter sensations. According to engineer Nimesha Ranasinghe, the simulator can also be used in computer games to allow people to share meals over the internet. The electrodes allow taste to be sent digitally. It does not require chemicals to be release by a computer, what previous attempts at the technology required.
“Digital taste is a technology for digitally simulating the sensation of taste. It uses two methods – electrical stimulation and thermal stimulation to stimulate the tip of the human tongue non-invasively in order to produce primary taste sensations such as salty, sour, sweet, bitter.
“By manipulating the magnitude of current, frequency, and temperature – both heating and cooling – thus far salty, sour, and bitter sensations have been successfully generated.
“Simulating food is one of the future directions of this technology.”
