Created cavity temperature sensor

An earring configured for insertion and being worn in an artificially-created human ear tissue cavity bounded by a first hole in ear tissue and a second hole in ear tissue opposite the first hole, the earring consisting of:

• an earring post;
• said earring post comprising an electronic temperature sensor;
• said earring post being dimensioned to be inserted through at least the first hole of the ear tissue and into the artificially-created ear tissue cavity;
• said electronic temperature sensor being configured, upon said earring post being inserted into the artificially-created ear tissue cavity, to provide a temperature measurement of the temperature within the artificially-created ear tissue cavity;
• an electronic transmitter configured to wirelessly transmit said temperature measurement;
• at least one power supply that powers said electronic temperature sensor and said electronic transmitter, wherein the power supply harvests energy from radio waves, Wi-Fi signals, or other signals and/or includes a battery;
• and
• at least one selected from the group consisting of a closure and at least one insulator configured to partially or completely enclose at least one of the first hole and the second hole of the artificially-created ear tissue cavity.

A belly button ring configured for insertion and being worn in an artificially-created human belly button tissue cavity bounded by a first hole in belly button tissue and a second hole in belly button tissue opposite the first hole, the belly button ring consisting of:

• a belly button ring post;
• said belly button ring post comprising an electronic temperature sensor;
• said belly button ring post being dimensioned to be inserted through at least the first hole of the ear tissue and into the artificially-created belly button tissue cavity;
• said electronic temperature sensor being configured, upon said belly button ring post being inserted into the artificially-created belly button tissue cavity, to provide a temperature measurement of the temperature within the artificially-created belly button tissue cavity;
• an electronic transmitter configured to wirelessly transmit said temperature measurement;
• and
• at least one power supply that powers said electronic temperature sensor and said electronic transmitter, wherein the power supply is at least one of a battery and a power supply that harvests energy from radio waves, Wi-Fi signals, or other signals.
