Summary
Flexible pressure sensors show promise for clinical monitoring, particularly in bed-based systems. However, inconsistent technical details and a need for standardized validation hinder their widespread adoption in healthcare.
Area of Science:
- Biomedical Engineering
- Materials Science
- Clinical Monitoring Technologies
Background:
- Flexible pressure sensors are increasingly explored for clinical monitoring.
- Existing research on their technical characteristics and applications is fragmented.
- Standardized reporting and validation are lacking for these advanced sensing solutions.
Purpose of the Study:
- To map literature on flexible pressure sensor matrices for biomedical applications.
- To identify technical characteristics and usage contexts of these sensors.
- To determine systems integrated into bed-based surfaces for clinical monitoring.
Main Methods:
- Scoping review following PRISMA-ScR guidelines.
- Systematic search of PubMed, Scopus, and Web of Science (2015-2025).
- Screening of 5021 records, with 45 studies included.
Main Results:
- Flexible pressure sensors predominantly utilize resistive and capacitive principles.
- Integrated systems focus on pressure distribution and posture monitoring in support surfaces.
- Significant heterogeneity and a lack of technical specifications were observed across studies.
Conclusions:
- Flexible pressure sensors offer significant potential for clinical monitoring applications.
- Standardized technological reporting is crucial for robust development.
- Clinical validation protocols are needed to translate sensor technology into reliable healthcare solutions.
