Wireless-activated Receptacle

I need a wireless-activated receptacle to complete an under-cabinet LED upgrade.

Replaced kitchen u.c florescent fixtures with LED strip lights; hard-wired an LED transformer (a.k.a, "driver") to existing switched circuit. I need to tie into this same circuit a LED strip light in an island. Kitchen is on-slab. Island has power, but access to conduit is near impossible without tearing apart the island.

I need a device that ties into the existing switched circuit which sends a wireless signal to a receiver within a purpose-designed receptacle to turn the island LED strip on/off with the rest of the circuit.

I've spent waaaay too much time keyword searching the Internet for a product that fits my application, but without luck. I'd appreciate responses with links to specific devices for me to consider.
