Japanese researchers have developed computerised chopsticks that enhance salty tastes, potentially helping those who need to reduce sodium in their diets.

Co-developed by Meiji University professor Homei Miyashita and beverage maker Kirin Holdings Co. the chopsticks enhance tastes using electrical stimulation and a mini-computer worn on a wristband.

The device uses a weak electrical current to transmit sodium ions from food, through the chopsticks, to the mouth where they create a sense of saltiness, said Miyashita.

“As a result, the salty taste enhances 1.5 times,” he said.

Miyashita and his lab have explored various ways that technology can interact with and stimulate human sensory experiences. He’s also developed a lickable TV screen that can imitate various food flavours.
