Source: Next-generation health monitoring: The role of nanomaterials in 3D-printed wearable devices
Wearable devices have been revolutionized by integrating nanomaterials and 3D printing. Washington State University reviewed nanomaterials’ properties, their roles in 3D printing, and the pros and cons of various 3D printing methods. This guide helps you understand how to integrate nanomaterials into 3D-printed wearable devices for next-generation healthcare monitoring.
- Understand nanomaterials. Nanomaterials, including carbon nanomaterials, metal nanomaterials, metal-organic frameworks, and biomaterials, enhance versatility, sensitivity, and overall performance due to their high surface-to-volume ratio.
- Select appropriate 3D printing techniques. Techniques like material extrusion, vat photopolymerization, and material jetting offer diverse fabrication methods, each with its advantages and limitations.
- Integrate nanomaterials into 3D printing inks. Carbon nanomaterials can be integrated with polymers to create conductive inks, while metal nanomaterials can be deposited on sensor electrode materials to improve electrochemical performance.
- Consider the application of the wearable device. Physiological parameter monitoring, biomedical signal monitoring, and metabolic status monitoring each require different nanomaterials and 3D printing techniques.
- Address challenges in nanomaterial dispersion. Use ex situ or in situ approaches to stabilize nanomaterials against aggregation when dispersing them in a polymer matrix. 6. Ensure safety and biocompatibility. Incorporate biocompatible nanomaterials, such as biomaterials, to develop safe and sustainable 3D-printed wearable monitoring devices.
