RCE uses patented light frequency technology to transdermally acquire a composite of cardiac biomarkers.
Our unique skin-derived approach, enhanced with deep learning techniques, analyzes and associates the transdermal derived optical signatures with cardiac conditions in real-time. This AI-coupled transdermal approach enables the potential application of our platform technology in various emergency care settings and remote monitoring applications.

Infrared Spectroscopy
Infrared spectroscopy is a widely used and applied characterization technique in the fields of geology, chemistry, and materials research has the ability to probe into a material at the molecular level. Molecular spectroscopy is one of the cornerstones of analytical tools used to study structural and compositional chemistry.
Our team of scientists have transformed the capabilities of this technology by discovering the interaction between mid-infrared (MIR) radiation with matter, and invented the world’s only mid-infrared spectrophotometric sensor configured within a wrist wearable.

Infrasensor™
Infrasensor™ is a non-invasive wrist-worn device intended for the detection of high-grade obstructive Non-ST Elevation Acute Coronary Syndrome (NSTE-ACS).
The device is intended to aid healthcare providers in evaluating symptomatic patients in acute care settings by providing supplemental information for the early identification of high-grade obstructive NSTE-ACS. High-grade obstructive NSTE-ACS includes acute coronary syndromes due to severe obstructive coronary artery disease, including total coronary artery occlusion.
The working principle of the Infrasensor™ is based on molecular infrared spectroscopy that uses an optical configuration called total internal reflection to assess a Transdermal Derived Infrared Spectrophotometric (TDIS) waveform. The detected infrared light waveform is transmitted from the on-device electronics unit to a secure cloud server where it is processed and analyzed to detect physiologic signals associated with high-grade obstructive NSTE-ACS.
Note: Infrasensor is currently an investigational device used for research purposes only. RCE is working closely with clinical and regulatory affairs to validate the safety and effectiveness prior to de novo pre-market clearance.

The future: Infrasensor-home

At RCE, we envision a future where cardiovascular disease can be better managed by patient’s cardiologist from the comfort of their own homes, providing peace of mind without the need for frequent visits to medical centers. To achieve this, we are developing a compact, wearable device that allows patients to continuously monitor their health in real-time. We believe this innovation will significantly enhance the quality of life for heart patients and substantially reduce health risks.
