Biocompatible and breathable healthcare electronics with sensing performances and photothermal antibacterial effect for motion-detecting

Abstract

With the booming development of smart wearable devices, flexible multifunctional composites with high sensitivity and well health therapy have evoked great interest for next-generation healthcare electronics. However, the weak biocompatibility, low breathability, and narrow sensing range greatly hinder the development of healthcare sensors. Herein, a porous, flexible and conductive MXene/Polydimethylsiloxane/Polydopamine/Polyurethane Sponge (MXene/PDMS/PDA/PU) nanocomposite is developed as a promising motion-detecting device with good flexibility, breathability, sensing performance, photothermal therapy and antibacterial activity. Benefiting from the porous structure and biocompatible surface, this multifunctional sensor is further fabricated into a diagnostic and therapeutic system for monitoring human body motion and performing hot therapy/antibacterial treatment in the application of sports injury site. Moreover, both the wireless smart insole and cushion are constructed to gait monitoring and sit position detecting. This multifunctional hybrid sponge not only demonstrates great potential for motion monitoring sensors but also exhibits wide potential in wearable medical assistive and therapeutic systems.

A multifunctional flexible strain sensor based on an excellent sensing performance PDMS-MXene@CNT/TPU nanofiber membrane with hydrophobic and photothermal conversion performance

“…However, PDMS-MXene@CNT/TPU nanofiber membranes have the capability to convert light energy into thermal energy when irradiated with infrared light. 49 The synergistic effect of the MXene and CNTs on photothermal conversion is evident, as illustrated in Fig. 5(a).…”

A nonradiographic strategy to real‐time monitor the position of three‐dimensional‐printed medical orthopedic implants by embedding superparamagnetic Fe3O4 particles

“…However, those radiographic investigations require special equipment and surgeons' professional experience and with a key inability to provide timely feedback in daily rehabilitation, [9] indicating the inconvenience for patients in both space and rehabilitation adjustment aspects. With the rapid development of wearable electronics, [10][11][12] sensing human motions, [13,14] especially for active bone movements, has generated interest by researchers in diverse fields. [15][16][17] Unfortunately, these new technologies can only achieve information of skin-based motions.…”

Capacitive Pressure Sensor Combining Dual Dielectric Layers with Integrated Composite Electrode for Wearable Healthcare Monitoring

“…Insole-based capacitive pressure sensors, in particular, are ideal for rehabilitation training and fall warning applications as they capture foot motion information, which is more accurate and stable than data from the wrist. 10 Furthermore, silver nanomaterials (e.g., silver nanowire and silver nanoparticles (AgNPs)) exhibit antibacterial and deodorizing effects, 32 and so insoles with introduced silver nanomaterials have the improved crucial properties of comfort, elasticity, and antibacterial activity. Inspired by the design of air columns in sports shoes, the introduction of air columns into pressure sensors also improves the flexibility and rebound resilience of the smart insoles.…”
