“…More direct applications include monitoring of chronic respiratory patients (e.g. patients diagnosed of COPD and/or asthma) for early detection of exacerbations, which is a life-saving application (see section 3 for further details) (Davies et al 2022 , Taylor et al 2023 ). Sleep respiratory disorders such as sleep apnea deserve special mention, because there is less movement and thus fewer motion artefacts during sleep than during daytime activity.…”

Photoplethysmography is a key sensing technology which is used in wearable devices such as smartwatches and fitness trackers. Currently, photoplethysmography sensors are used to monitor physiological parameters including heart rate and heart rhythm, and to track activities like sleep and exercise. Yet, wearable photoplethysmography has potential to provide much more information on health and wellbeing, which could inform clinical decision making. This Roadmap outlines directions for research and development to realise the full potential of wearable photoplethysmography. Experts discuss key topics within the areas of sensor design, signal processing, clinical applications, and research directions. Their perspectives provide valuable guidance to researchers developing wearable photoplethysmography technology.

“…This wearable technology is different from smart watches, rings, or glasses (smart accessories) as the tech in garments sits within elastic shirts or trousers. Therefore, these garments impose higher demands on wearability and signal processing [6]. While smart accessories already have a large market share, smart garments are awaiting further investments in research and development to potentially break through into the commercial market [7].…”

BACKGROUND Long term unobtrusive monitoring of breathing patterns can potentially give a more realistic insight into the respiratory health of people with asthma or chronic obstructive pulmonary disease than brief tests performed in medical environments. However, it is uncertain whether users would be willing to wear these sensor garments long term. OBJECTIVE Our objective was to explore whether users would wear knitted garments with knitted-in breathing sensors long term to monitor their lung health and under what conditions. METHODS Multiple knitted breathing sensor garments, developed and fabricated by the research team, were presented during a demonstration. Participants were encouraged to touch and feel the garments and ask questions. This was followed by two semi-structured, independently led focus groups with a total of 16 participants of which 4 had asthma. The focus group conversations were recorded and transcribed. Thematic analysis was carried out by three independent researchers in three phases consisting of: familiarization with the data, independent coding and overarching theme definition. Participants also completed a web-based questionnaire to probe opinion about wearability and functionality of the garments. Quantitative analysis of the sensors’ performance was mapped to participants’ garment preference to support the feasibility of the technology for long term wear. RESULTS Key points extracted from the qualitative data were: 1) garments more likely to be worn if medically prescribed, 2) cotton vest as underwear was preferred, and 3) a breathing crisis warning system was seen as a promising application. The qualitative analysis showed a preference for loose short sleeved T-shirts with a 81% acceptability rate, a 69% acceptability rate for snug fitting garments and 0% for tight-fitting garments. 62% of the participants would wear the knit for the whole day and 81% only during the night if not too hot. The sensitivity demands on the knitted wearable sensors can be aligned with users’ garment preferences. CONCLUSIONS There is an overall positive opinion about wearing a knitted sensor garment over a long period of time for monitoring of respiratory health. The knit cannot be tight but should be able to be worn as a vest as underwear in a breathable material. These requirements can be fulfilled with the proposed garments. Participants with asthma supported using it as a sensor garment connected to an asthma attack alert system.

“…The use of monitoring patients for asthma was analyzed [121]. Electrocardiogram and photoplethysmogram signals are widely used in smartwatches and breast bracelets, making it easy to integrate a more extensive body sensor system to predict asthma exacerbations.…”

This study conducted a comprehensive patent and bibliometric analysis to elucidate the evolving scientific landscape surrounding the development and application of pulse oximeters, including in the field of digital medicine. Utilizing data from the Lens database for the period of 2000–2023, we identified the United States, China, the Republic of Korea, Japan, Canada, Australia, Taiwan, and the United Kingdom as the predominant countries in patent issuance for pulse oximeter technology. Our bibliometric analysis revealed a consistent temporal trend in both the volume of publications and citations, underscoring the growing importance of pulse oximeters in digitally-enabled medical practice. Using the VOSviewer software(version 1.6.18), we discerned six primary research clusters: (1) measurement accuracy; (2) integration with the Internet of Things; (3) applicability across diverse pathologies; (4) telemedicine and mobile applications; (5) artificial intelligence and deep learning; and (6) utilization in anesthesiology, resuscitation, and intensive care departments. The findings of this study indicate the prospects for leveraging digital technologies in the use of pulse oximetry in various fields of medicine, with implications for advancing the understanding, diagnosis, prevention, and treatment of cardio-respiratory pathologies. The conducted patent and bibliometric analysis allowed the identification of technical solutions to reduce the risks associated with pulse oximetry: improving precision and validity, technically improved clinical diagnostic use, and the use of machine learning.
