1. A wearable device for intradermal delivery of a drug comprising:
a microneedle array comprising a plurality of microneedles,
wherein each microneedle of the microneedle array comprises the drug, a light-to-heat transducing element, and a polymer;
at least one light source comprising a light emitting diode; and
a controller to operate the at least one light source,
wherein light energy emitted from the at least one light source is absorbed by the light-to-heat transducing element, causing a rise in temperature that melts the polymer and releasing the drug.
