Wearable pores and skin patch displays hemoglobin in deep tissues

A workforce of engineers has developed a photoacoustic patch that may monitor biomolecules in deep tissues, together with hemoglobin. It may carry out 3D mapping of hemoglobin with a submillimeter spatial decision in deep tissues, all the way down to centimeters beneath the pores and skin, versus different wearable electrochemical units that solely sense the biomolecules on the pores and skin floor.
