I. Introduction
E-Skin for Neonatal Health Monitoring
1.1 Research Background
Neonatal health is critical to their future growth and development and weighs heavily on every family. According to data from the World Health Organization, approximately 2.5 million newborns worldwide die within the first 28 days of life each year, mostly due to abnormal body temperature, cardiopulmonary dysfunction and other related conditions. Neonates have underdeveloped physical functions, especially in the skin: the stratum corneum is thin, and the connection between the epidermis and dermis is loose, resulting in extremely fragile and sensitive skin with poor resistance to external irritants.
Traditional neonatal health monitoring methods, including mercury thermometers for temperature measurement and stethoscopes for cardiopulmonary examination, are not only inconvenient to operate and incapable of real-time monitoring but also may damage the delicate neonatal skin due to frequent physical contact.
With the rapid advancement of science and technology, electronic skin (e-skin) technology has emerged, bringing new breakthroughs to neonatal health monitoring. As an innovative wearable device, e-skin features flexibility and adhesion similar to human skin, enabling non-invasive, real-time monitoring of human physiological parameters. When applied to neonatal care, e-skin effectively addresses the limitations of traditional monitoring methods. It continuously and accurately tracks vital signs such as body temperature, heart rate, respiratory rate and blood oxygen saturation, providing medical staff and parents with timely and accurate health data. This allows early detection of potential health risks and prompt intervention, greatly upgrading neonatal health protection capabilities and carrying transformative significance for the industry.

II. Technical Analysis of Neonatal Health Monitoring E-Skin
2.1 Core Technical Principles
2.1.1 Composition and Properties of Ultra-Thin Breathable Materials
The neonatal health monitoring e-skin is fabricated from composite materials combining thermoplastic polyurethane (TPU) and silk fibroin (SF). TPU is a multifunctional thermoplastic polymer composed of hard and soft segments. Carbamate groups in hard segments form intermolecular hydrogen bonds, endowing the material with high tensile strength, wear resistance and heat resistance; soft segments made of polyether, polyester or mixtures deliver excellent elasticity. With a hardness range of Shore A 65 – 85D, tensile strength of 30 – 60 MPa and elongation at break of 300% – 700%, TPU offers outstanding wear resistance and biocompatibility, reducing skin irritation for neonates. Silk fibroin, extracted from silkworm cocoons, features superior processability, tunable physical properties, excellent biocompatibility and biodegradability.
Adopting specialized manufacturing processes, the thickness of the e-skin is controlled below 0.1 mm. For instance, the nano-network reinforced ultra-thin ion gel film co-developed by Hunan University of Technology and Zhengzhou University reaches merely 12 micrometers. The ultra-thin design delivers exceptional flexibility and skin conformability, adhering closely to the neonatal chest or back with near-zero sensory interference. It possesses an ultra-high water vapor transmission rate of 2464.4 g·m⁻²·day⁻¹, mimicking the respiratory function of human skin. This effectively prevents skin redness and discomfort caused by sweat accumulation and allows the neonatal skin to breathe freely. Moreover, the high stretchability adapts to daily limb movements and physical growth of neonates, maintaining stable performance under moderate stretching to guarantee continuous and accurate monitoring.
2.1.2 Physiological Parameter Monitoring Mechanisms
Integrated with diverse high-sensitivity sensors, the e-skin realizes precise monitoring of multiple vital signs.
- Body Temperature Monitoring: Thermal sensors such as thermistors and thermocouples function based on temperature-dependent changes in material resistance or electric potential. Upon contact with neonatal skin, sensors capture surface temperature variations, convert thermal signals into electrical outputs, and deliver real-time temperature data through accurate signal processing.
- Heart Rate Monitoring: Photoplethysmography (PPG) technology is applied. PPG sensors emit specific-wavelength light onto the skin, which is absorbed, reflected and scattered by tissues. Periodic changes in blood volume and composition caused by heartbeat lead to fluctuating reflected light intensity. Sensors capture these optical variations, convert them into electrical signals, and calculate heart rate via algorithmic analysis.
- Respiratory Rate Monitoring: Strain sensors or capacitive sensors detect subtle thoracic and abdominal deformation during breathing. Respiratory movements cause structural changes in sensors, resulting in variations in resistance or capacitance, which are measured to calculate respiratory frequency.
- Blood Oxygen Saturation Monitoring: Dual-wavelength optical technology utilizes differential light absorption characteristics of oxyhemoglobin and deoxyhemoglobin under red and infrared light. By detecting transmitted or reflected light intensity, complex algorithms calculate arterial blood oxygen saturation.
2.2 Key Technological Innovations
2.2.1 Ultra-Thin and Breathable Design
Traditional neonatal monitoring devices are bulky and incapable of continuous tracking. Most conventional wearable monitors are thick and poorly ventilated, easily causing skin irritation and discomfort after long-term wear. Typical wearable heart rate monitors have a thickness of 1–2 mm, and friction during infant activities frequently triggers redness and allergies.
In contrast, the e-skin, thinner than 0.1 mm, acts as a lightweight secondary skin with minimal restriction on neonatal movement. Its high air permeability accelerates sweat evaporation to keep the skin dry, significantly improving wearing comfort, reducing adverse skin reactions and achieving imperceptible long-term monitoring.
2.2.2 Multi-Parameter Real-Time Monitoring
Commercially available neonatal monitors often only support single-indicator detection, failing to reflect overall health conditions comprehensively. This e-skin synchronously monitors body temperature, heart rate, respiratory rate and blood oxygen saturation. Comprehensive multi-dimensional data analysis enables medical staff and parents to assess neonatal health accurately. For example, fever is usually accompanied by accelerated heart rate, rapid breathing and fluctuating blood oxygen levels. Synchronous monitoring enables early anomaly identification, provides evidence for early diagnosis and treatment, and avoids delayed medical intervention caused by single-parameter limitations.
2.2.3 Intelligent Alarm and Linkage System
When monitoring data exceeds preset normal ranges (such as hyperthermia, arrhythmia and tachypnea), built-in intelligent algorithms trigger immediate judgment. Via Bluetooth and other wireless communication technologies, real-time alarm notifications with specific abnormal indicators and values are pushed to parental mobile APPs, accompanied by sound and vibration reminders for timely awareness.
Furthermore, the e-skin achieves intelligent linkage with crib constant temperature systems. Abnormal temperature data is automatically transmitted to the temperature control device, which adjusts the ambient temperature intelligently to maintain a comfortable and stable environment for neonates, assist physical recovery and reduce health risks induced by inappropriate environmental temperatures.
2.2.4 Washable and Size-Adaptive Design
Constructed with high-stability polymer materials, the e-skin features excellent water resistance and structural stability, maintaining intact performance after repeated washing. Sealed packaging technology protects internal sensors and circuits from water damage, while a streamlined structure prevents dirt residue and facilitates daily cleaning.
To accommodate rapid neonatal growth, the main body adopts stretchable materials combined with adjustable accessories such as hook-and-loop fasteners and elastic bands for flexible size modification. Multiple size specifications are also available to meet the needs of neonates at different growth stages, ensuring stable adhesion and consistent monitoring accuracy throughout infancy.
III. Application Scenarios and Case Analysis
