1. An energy harvesting tape comprising:
a plurality of flexible layers including:
a solar cell layer configured to capture solar energy,
a thermoelectric layer configured to capture thermal energy,
one or more piezoelectric layers configured to capture mechanical energy; and
an electrode layer configured to capture radiofrequency energy and to transmit a radiofrequency signal; and
one or more processing units on at least one of the plurality of flexible layers, the one or more processing units being configured to use the captured energy from the plurality of flexible layers to transmit the radiofrequency signal; and
wherein the energy harvesting tape has a length, a width, and a thickness, where the length is greater than the width, and the width is greater than the thickness.
