A Prototype Wearable Device for Noninvasive Monitoring of Transcutaneous Oxygen

Optimization of Transcutaneous Oxygenation Wearable Sensors for Clinical Applications

“…[ 17–20 ] Promising current research involves the use of low‐power electronics, with the proposed devices being based on both intensity of lifetime, although more work is required to optimize the ergonomics and portability of the devices. [ 21–26 ] Recently, we reported on the first fully self‐contained wearable transcutaneous oxygen sensor. [ 27,28 ] The simplicity of the device was possible due to the use of an ultrabright porphyrin molecule [ 29 ] that produces long‐lasting phosphorescence (≈ 10 − 100μs) detectable with commodity electronic hardware.…”

Editors’ Choice—Luminescent Oxygen Sensors: Valuable Tools for Spatiotemporal Exploration of Metabolism in In Vitro Systems

“…This sensing mechanism has gained traction in a variety of fields and has proven to be applicable for both in vitro studies of cell metabolism and in vivo applications for physiological monitoring with implantable or wearable transcutaneous devices. While transcutaneous devices for physiological O 2 monitoring have made significant progress in recent years, [11][12][13][14][15] this perspective will mainly focus on the in vitro use of luminescent sensors that are quenched by O 2 with the main goal of guiding the reader towards a logical sensor choice for their desired application. As such, we are not attempting to review the entire field of O 2 sensing for metabolic evaluation, but rather to provide the reader with examples of what is possible to help guide their research and facilitate innovation in this domain.…”
