In a small study, the microchip was used to deliver osteoporosis medication to women who otherwise would have to inject the drug.
The device has a wireless receiver that signals the microchip to release the drug all at once, much like an injection would.
The company, Microchips Incorporated, hopes to have a version of the device on the market in five years.
Researchers say it has the potential or other uses such s treating diabetes or delivering cancer drugs.
