Scientists in Japan have created a soft robotic tongue capable of mimicking the sensation of a real human lick.
The device reproduces natural motion, pressure, and texture in a surprisingly lifelike way, opening new possibilities for medical training, sensory research, and future human‑like machines designed to interact more naturally with people.
At the core of the system is a flexible, muscle‑like material that can adjust pressure, speed, and direction to replicate human touch. This makes it a powerful tool for studying how people perceive sensations and for improving how robots interpret physical interaction.
The technology could transform medical education by allowing students to practice safely without relying on real patients. It may also play a role in advanced robotics labs, prosthetics, and immersive virtual‑reality systems where realistic tactile feedback is essential.
Researchers say this invention reflects a broader shift in robotics toward more human‑centered design. Instead of rigid, mechanical devices, engineers are building systems that feel more natural and intuitive. As development continues, future versions are expected to become smaller, more affordable, and widely accessible — with early adoption in hospitals likely within the next few years.
