The term “electronic skin,” often referred to as “e-skin” or “electronic dermis,” describes an elastic and flexible electronic system that replicates the features and characteristics of human skin. In order to detect and react to various physical stimuli, it integrates sensors, actuators, and other electrical components with a soft and flexible substrate, much like how human skin senses and engages with the environment.
Due to its potential use in industries like robotics, healthcare, prosthetics, virtual reality, and human-machine interfaces, e-skin has attracted a lot of attention lately. E-skin enables a variety of fascinating features by integrating electrical components onto a flexible and conformable substrate, enabling seamless integration with the human body. The capacity of e-skin to detect varied physical stimuli is one of its primary characteristics. This includes variations in strain, pressure, temperature, humidity, and even chemicals.
The e-skin has sensors built into it that can measure and detect various variables, including strain gauges, temperature sensors, and pressure sensors. This functionality is especially beneficial in applications like patient monitoring in healthcare, where e-skin can be used to watch vital signs, gauge body temperature, and keep an eye on patients’ movements and activities.
The capacity of the e-skin to react to stimuli using actuators and electronic components is another crucial feature. Piezoelectric materials, conductive polymers, and shape memory alloys are just a few examples of the components that can be used in an e-skin to provide mechanical motion, and vibration, or even to administer controlled drug release. Applications in haptic feedback systems, wearable robotics, and intelligent prosthetics are made possible by this characteristic.
The progress of elastic, flexible materials as well as production methods is essential to the development of e-skin. To guarantee the flexibility, stretchability, and durability of the e-skin, materials with special mechanical qualities, including elastomers, polymers, and nanomaterials, are used. These materials give the e-skin the flexibility to bend and stretch repeatedly without losing its usefulness while also allowing it to adjust to uneven surfaces.
When it comes to fabrication, several methods are used to create e-skin. These include microfabrication processes to produce tiny sensors and circuits, as well as printing technologies like inkjet or screen printing to deposit functional materials onto the flexible substrate.
The development of e-skin has also benefited from developments in nanotechnology and nanomaterial fabrication, which have made it possible to integrate nanoscale components and improved the sensitivity and performance of the sensors. E-skin has a plethora of different possible uses. Robotic systems can interact with items and people more successfully by using e-skin to improve their tactile sensing capabilities.
E-skin in healthcare can be used for ongoing patient health monitoring, early skin disease identification, or the creation of smart bandages that offer real-time input on wound healing. E-skin can be incorporated into artificial limbs or other prosthetic devices in the field of prosthetics, allowing amputees to restore their sense of touch and dexterity. E-skin can be used to create more immersive experiences through haptic feedback in virtual reality and gaming applications.
Even though e-skin has a lot of potential, obstacles still need to be overcome. Additional study and development are needed in the areas of achieving long-term stability and durability, guaranteeing biocompatibility for medical applications, and enhancing the integration of power sources and wireless communication.
The sensing and interacting characteristics of human skin are replicated by electronic skin, a cutting-edge technology. E-skin, which is stretchy and flexible, has the potential to improve a number of industries, including virtual reality, robotics, healthcare, and prosthetics. E-skin has the potential to open up new applications and improve how people interact with the digital environment as technology develops.
The Global Electronic Skin Market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
To help people recognize the shape and texture of items, researchers at the Korea Institute of Machinery and Material in Daejeon, South Korea, have developed an e-skin for prosthetic hands that can detect the intensity of force and pressure. The Wearable Electronics Sector’s High Demand for Electronic Skin Solutions Is Anticipated to Be a Key Growth Driver
A physicist has created a multimodal hybrid material called electronic skin. The recently created “smart skin” resembles human skin extremely much. It generates electronic signals while concurrently sensing pressure, humidity, and temperature. Thus, it is possible to create robots that are more sensitive or smarter prosthetics.
The “smart skin” created by Anna Maria Coclite resembles human skin a great deal. It generates electronic signals while concurrently sensing pressure, humidity, and temperature. Thus, it is possible to create robots that are more sensitive or smarter prosthetics.
Several recent developments in the field of electronic skin, or “e-skin,” are discussed, with an emphasis on the technology required for the three main applications of skin-attachable electronics, robotics, and prosthetics.
First, materials with inherent stretchability and self-healing characteristics are crucial since e-skin will be subjected to repeated stresses of various kinds and needs to be conformally bonded to unevenly shaped surfaces.
Second, tactile sensing abilities including the detection of pressure, strain, slide, force vector, and temperature are crucial for skin-attachable devices that monitor health as well as for robotics and prosthetics that require the capacity to manipulate objects and sense their surroundings. Chemical and electrophysiological sensing, as well as wireless signal communication, are crucial for skin-attachable devices to accurately assess users’ health and maintain their comfort.
