Virtual Hug, A Wireless, Soft E-Skin Enables Interactive Touch Communication In The Virtual World


In the near future, it may be possible to feel the sensation of a virtual hug through the internet.

This exciting prospect could revolutionize the way we connect with loved ones who are far away.

Imagine being able to physically feel the embrace of a friend or family member, even if they are on the other side of the world.

While this technology is not yet available, it is an exciting development to keep an eye on.

Who knows what other incredible advancements in communication and connection we will see in the coming years?


What’s this magical skin?

The e-skin is a cutting-edge technology that boasts an array of 16 flexible actuators, also known as sensors, arranged in a 4 x 4 configuration.

This innovative device also features a microcontroller unit (MCU), a Bluetooth module, and other advanced electronics, all integrated into a flexible circuit board.

The e-skin is poised to revolutionize the way we interact with technology, offering unparalleled flexibility and versatility.

Imagine a small, skin-patch-like device that measures only 7cm by 10cm and is 4.2mm thick.

This device combines all the necessary components into one compact package. It’s amazing how technology has advanced to allow for such a small yet powerful device.
The e-skin’s core component is a button-like actuator, which is approximately the same size as a 10-cent coin in Hong Kong. This small but essential part is what makes the e-skin function properly.

Actuators are an essential component of touch sensing and haptic feedback systems.

They are responsible for converting electrical signals into physical sensations that users can feel.

In these systems, actuators consist of several parts, including a flexible coil, a soft silicone support, a magnet, and a thin polydimethylsiloxane (PDMS) film.

These components work together to create the desired tactile experience through electromagnetic induction.

By using this technology, users can interact with devices in a more intuitive and engaging way, making touch sensing and haptic feedback systems an increasingly popular choice for a wide range of applications.

The term "electronic skin" is used to describe electronics that are flexible, elastic, and self-healing, and that can therefore imitate the functions of biological skin.

Soft E-Skin with Touch Detection and Delivery Capability

The latest breakthrough in the field of technology comes from the research team at City University of Hong Kong (CityU).

They have successfully developed a wireless, soft e-skin that has the ability to detect and deliver the sense of touch.

This innovative technology also allows for the formation of a touch network, enabling one-to-multiuser interaction.

The possibilities of this development are endless and could revolutionize the way we interact with technology.

Distance touch communication has the potential to be even more immersive with the right tools.

what should we expect?

E-skin technology has been making waves in the fields of robotics and prosthetics. One of the key components of e-skin patches is the actuator, which is responsible for providing tactile feedback to the user.

When an external force is applied to the actuator, it is pressed and released, inducing a current that generates electrical signals.

These signals are then transmitted to a corresponding actuator in another e-skin patch, providing the user with a sense of touch.

This technology has the potential to revolutionize the way we interact with machines and prosthetic devices, making them more intuitive and responsive to our needs.

When it comes to e-skin technology, the level of pressure applied by the sender directly correlates to the intensity and duration of the sensation felt by the receiver.

This means that the deeper the sender presses, the more powerful the resulting sensation will be on the other person’s e-skin.

This innovative technology has the potential to revolutionize the way we communicate and interact with each other in the digital age.

Finally, a virtual hug and silky e-skin technology are fascinating. This technique could transform our digital interactions.

Distance touch communication could be more immersive with touch detection and delivery.

This technology is intriguing to watch in the future. Technology may someday allow us to feel the embrace of distant loved ones, changing how we communicate.

E-skin technology could make machines and prosthetics more intuitive and responsive to our demands.

New communication and connection ways are unlimited as technology advances at an unparalleled rate.

still, wondering?

Pressure, temperature, humidity, and airflow can all be monitored thanks to the integrated sensors in E-skin, as reported by It aids in the body’s readjustment process following a transplant. Robots can be made more humane with their help. With the use of thin electrical wires, the skin may produce impulses that are physiologically identical to those produced by the nervous system.

The Bendable Electronics and Sensing Technologies (BEST) Group at the University of Glasgow, directed by Professor Ravinder Dahiya, has developed the electronic skin, the latest advance in flexible, elastic printed surfaces.
