A system for detecting abnormal events in humans includes a main body in contact with the human skin surface, a heating source for heating the skin surface to a target temperature, and the temperature of the skin surface in contact with the heating source. a blood volume sensor for measuring skin surface blood volume; hardware communicatively coupled to the heating source, the blood volume sensor, the skin temperature sensor, and the environmental temperature sensor; a hardware processor; The hardware processor receives a baseline blood volume signal, initiates a heating cycle by outputting a heating signal to the heating source, and receives a second blood volume signal from the blood volume sensor. , to compare the second blood volume signal to the baseline blood volume signal to determine whether an abnormal biological event has occurred.
