1. A finger temperature indicating ring for indicating a physically or mentally relaxed condition of a wearer, comprising:

  • a ring body including a band portion having a lower opening forming two lower ends of said ring body, and two symmetric channels circumferentially embedded in two opposite sides of said band portion to respectively receive an arcuated thermal conductive rod and an arcuated discharge rod therein, said thermal conductive rod and said discharge rod having lower ends which respectively project from an inner side of said two lower ends of said ring body, forming two exposed ends to touch an outer periphery of the wearer'"'"'s finger when said finger temperature indicating ring is worn around the wearer'"'"'s finger; and

    said band portion having a shallow top recess for accommodating electronic elements of said ring therein;

    a top cover having a contour corresponding to a contour of said top recess on said ring body for fitly covering said ring body and engaging with said top recess, and said top cover being formed at a top surface with several openings;

    a top panel being disposed in a space defined between said top cover and said top recess of said ring body, said top panel being provided at an upper surface with a switch button, an on/off button, a liquid crystal display, and an LED which respectively project from said openings formed on said top cover; and

    a circuit board electrically connected to a bottom side of said top panal and including a thermistor, an indicating element, and other relevant electronic elements;

    wherein said thermistor is connected to a top end of said thermal conductive rod and may therefore sense a finger temperature of the wearer via said exposed end of said thermal conductive rod and actuate an operation in said circuit board to convert said finger temperature sensed by said thermistor into a signal, said signal corresponding to said physically or mentally relaxed condition of the wearer and being sent to said indicating element which presents said signal to the wearer in at least one of the following manners selected via said switch button on said top panel;

    a. causing said discharge rod to discharge a small amount of electric current strong enough for the ring wearer to perceive it;

    b. causing said liquid crystal display to show a value of said finger temperature sensed by said thermistor;

    c. causing said LED to emit light;

    ord. warning the ring wearer by other equivalent element.
