Special Issue Information

Dear Colleagues,

Advances in material science, bioinstrumentation, and signal processing and analysis have provided novel sensing technologies that are compliant, discreet, and more comfortable to adopt for use in biomechanical applications such as injury prevention, recovery, performance enhancement, etc. Flexible wearable sensors combined with advanced machine learning or artificial intelligence allow for advancements in the diagnosis, monitoring, and prediction of changes in physical function and health.

This Special Issue, “Flexible Wearable Sensors for Biomechanical Applications”, will aim to showcase original contributions that explore the use of flexible wearable sensors for biomechanical applications, covering a wide range of topics, including but not limited to the following:

  • Novel devices or flexible wearable sensors for biomechanical applications;
  • Use of flexible wearable sensors in biomechanical applications, such as injury prevention, recovery, or performance enhancement, among others;
  • Innovative sensor design, programming, or integration to enhance the performance, usability, and wearability of flexible sensors;
  • Integration of flexible wearable sensors for multi-domain approaches to biomechanical analyses;
  • Novel algorithms and methods for processing, analyzing, and interpreting flexible wearable sensor data.

This study investigates the feasibility of using a wearable system with full-wave alternating current (AC) excitation to measure electrodermal activity (EDA). Typically measured using direct current (DC) excitation, EDA is often affected by signal drift due to electrode–skin polarisation. To address this, a portable device was developed that applies fixed-amplitude, full-wave AC signals and records EDA under controlled conditions. The electrical behaviour of the skin was also simulated using a multilayer model to analyse current propagation at different frequencies. The experimental procedure was conducted with ten healthy participants under controlled conditions. Two stages were carried out: the first compared the similarity of the skin conductance level (SCL) between DC and half-wave alternating current (AC) signals; the second analysed signal stability and skin response at full-wave AC excitation. Compared to DC, full-wave AC excitation demonstrated reduced signal drift, greater temporal stability, and enhanced measurement of the skin’s capacitive response. These findings support the adoption of AC excitation for EDA measurement, especially in ambulatory and real-time biomechanical applications where signal reliability and stability are essential.
