Special Issue Information

Dear Colleagues,

The recent advances and achievements in the fields of material science and fabrication technologies open new potential applications of wearable systems for distributed sensing with smart capabilities. The miniaturization of devices, the ultra-low power consumption requirements of modern sensors and the growing need of new solutions in the field of Ambient Assisted Living, in terms of unobtrusive sensing devices for health and indoor ambient monitoring, drive the development of smart body patches and fabric-coupled multisensorial platforms. A growing interest is focused on the nanostructured sensing materials for flexible substrates, scalable and cost-effective fabrication techniques and smart packaging solutions for distributed sensing systems, supporting also the environmental protection policies. These complex systems may require in addition an energy independence to fulfil the above needs and an intrinsic energy harvesting capability.

This Special Issue, the first MDPI Special Issue focused on the wearable chemical sensing domain to date, aims to focus and report the recent advances in the wearable chemical sensing field, including innovative nanomaterials and in-situ materials growth/deposition, micro and nanofabricated devices, textile and body patches reliability issues, energy harvesting and high efficiency data transfer solutions.

Contributions may include, but are not limited to:

  • Innovative wearable chemical sensor devices
  • Nanostructured materials for chemical sensing
  • Real energy autonomous wearable systems for chemical sensing
  • Fabric and body patch sensors integration, wearing/reliability issues
  • Innovative zero power optical, physical, electrical detection techniques for wearable sensing

Flexible physiological medical devices have gradually spread to the lives of people, especially the elderly. Here, a flexible integrated sensor based on Au nanoparticle modified copper hydroxide nanograss arrays on flexible carbon fiber cloth (Au@Cu(OH)2/CFC) is fabricated by a facile electrochemical method. The sensor possesses ultrahigh sensitivity of 7.35 mA mM−1 cm−2 in the linear concentration range of 0.10 to 3.30 mM and an ultralow detection limit down to 26.97 nM. The fantastic sensing properties can be ascribed to the collective effect of the superior electrochemical catalytic activity of nanograss arrays with dramatically enhanced electrochemically active surface area as well as mass transfer ability when modified with Au and intimate contact between the active material (Au@Cu(OH)2) and current collector (CFC), concurrently supplying good conductivity for electron/ion transport during glucose biosensing. Furthermore, the device also exhibits excellent anti-interference and stability for glucose detection. Owing to the distinguished performances, the novel sensor shows extreme reliability for practical glucose testing in human serum and juice samples. Significantly, these unique properties and the soft structure of silk fabric can provide a promising structure design for a flexible micro-device and a great potential material candidate of electrochemical glucose sensor.
