Special Issue Information

Dear Colleagues,

Wearable devices have a variety of applications in many different areas, including healthcare, fitness, assisted living, sports, remote monitoring, and rehabilitation. However, realization of truly wearable devices is only possible by having sensors within these devices (i.e., wearable sensors) that can sense data continuously in an unobtrusive way over long periods of time while being worn by patients and other users. These may be in the form of textile fabric, flexible patch, skin attachment or an implant and sense a range of physiological and environmental parameters. The key issues in the design of wearable sensors include their sensing accuracy, size, flexibility, and power consumption. These aims are very challenging to achieve and require further research in to novel sensing materials and their electrical and mechanical characteristics. Consequently, this Special Issue of Polymers invites high-quality research and review articles highlighting the advances in wearable sensors and their properties with particular emphasis on biomedical and healthcare applications.

Contributions may include, but are not limited to:

  • Flexible sensors for wearable and implantable devices
  • Innovative applications of wearable sensors
  • Wearable sensors for biomedical applications
  • Advances in materials for polymer-based sensors
  • Demonstration and characterization of full systems using wearable sensors

Polychloro-para-xylylene (parylene-C) is a flexible and transparent polymer material which has excellent chemical stability and high biocompatibility. Here we demonstrate a polymer device based on single-component parylene-C with memory and temperature sensing functionalities. The device shows stable bipolar resistive switching behavior, remarkable storage window (>104), and low operation voltages, exhibiting great potential for flexible resistive random-access memory (RRAM) applications. The I-V curves and conductive atomic force microscopy (CAFM) results verify the metallic filamentary-type switching mechanism based on the formation and dissolution of a metal bridge related to the redox reaction of the active metal electrode. In addition, due to the metallic properties of the low-resistance state (LRS) in the polymer device, the resistance in the LRS exhibits a nearly linear relationship at the temperature regime between 25 °C and 100 °C. With a temperature coefficient of resistance (TCR) of 2.136 × 10−3/°C, the device is also promising for the flexible temperature sensor applications. Full article

Wearable human interaction devices are technologies with various applications for improving human comfort, convenience and security and for monitoring health conditions. Healthcare monitoring includes caring for the welfare of every person, which includes early diagnosis of diseases, real-time monitoring of the effects of treatment, therapy, and the general monitoring of the conditions of people’s health. As a result, wearable electronic devices are receiving greater attention because of their facile interaction with the human body, such as monitoring heart rate, wrist pulse, motion, blood pressure, intraocular pressure, and other health-related conditions. In this paper, various smart sensors and wireless systems are reviewed, the current state of research related to such systems is reported, and their detection mechanisms are compared. Our focus was limited to wearable and attachable sensors. Section 1 presents the various smart sensors. In Section 2, we describe multiplexed sensors that can monitor several physiological signals simultaneously. Section 3 provides a discussion about short-range wireless systems including bluetooth, near field communication (NFC), and resonance antenna systems for wearable electronic devices. Full article
