Smart wearables provide an unprecedented opportunity to monitor health and fitness unobtrusively in daily life. Devices such as smartwatches, smart bands, and smart rings use the technique of photoplethysmography to measure the pulse wave, from which a wealth of physiological information can be derived. Consequently, much research focuses on developing wearable photoplethysmography technologies for health and fitness applications, such as detecting abnormal heart rhythms and monitoring blood pressure. In this talk, Peter Charlton will summarise the findings of ‘The 2023 Wearable Photoplethysmography Roadmap’, an article in which 51 leading researchers in the field of photoplethysmography provided their insights into the key research required to realise the full potential of wearable photoplethysmography. He will also highlight recent developments in the field, using examples from his own research.
