More sensitive and durable haptic sensors are at the heart of robotics developments.Researchers at Chung-Ang University in South Korea have developed piezoelectric and triboelectric haptic sensors that could revolutionize the fields of robotics and wearables.

What does the next generation of haptic sensors for robots promise?

The new study looks at the materials and manufacturing methods used to improve the performance of self-powered sensors. These sensors are vital for a wide range of applications, from medical monitoring to human-machine interfaces. But it has long faced endurance challenges.

Piezoelectric sensors, which generate electricity in response to mechanical stress, and triboelectric sensors, which work through contact-induced charge transfer, each offer their own unique advantages. The researchers addressed issues such as material fragility and environmental constraints.

“Our work describes material and device fabrication strategies for haptic sensors using piezoelectric and triboelectric effects, as well as types of sensory recognition. “These strategies are important for applications in robotics, wearables and healthcare systems.
