Monitoring Hemoglobin in Deep Tissues #WearableWednesday

Engineers at University of California San Diego have developed a photoacoustic sensor that could help monitor hemoglobin and core temperature.

Low blood perfusion inside the body may cause severe organ dysfunctions and is associated with a range of ailments, including heart attacks and vascular diseases of the extremities. At the same time, abnormal blood accumulation in areas such as in the brain, abdomen or cysts can indicate cerebral or visceral hemorrhage or malignant tumors. Continuous monitoring can aid diagnosis of these conditions and help facilitate timely and potentially life-saving interventions.

The new sensor overcomes some significant limitations in existing methods of monitoring biomolecules. Magnetic resonance imaging (MRI) and X-ray-computed tomography rely on bulky equipment that can be hard to procure and usually only provide information on the immediate status of the molecule, which makes them unsuitable for long-term biomolecule monitoring.
