Rumors regarding the development of a 'digital pill' with a microchip inside have been circulating for some time, but today, the FDA actually green lighted the product. The company, Proteus Digital Health, gained FDA approval for its 1 square millimeter device (the size of a grain of sand), which it believes will "shift the care paradigm" into an era of digital medicine.

According to Proteus Digital Health's website: Digital Medicines are the same pharmaceuticals you take today, with one small change: each pill also contains a tiny sensor that can communicate, via our digital health feedback system, vital information about your medication-taking behaviors and how your body is responding.

The company added "As a result, you can be sure you're taking your medicines as prescribed, while at the same time receiving unprecedented feedback on your physical response to treatment."

The aim of the "ingestible sensor" is to electronically verify patient compliance in taking the medication. Proteus Digital Health estimates that over 50% of patients do not get the full benefit from the pharmaceuticals they take because of taking the wrong dose or taking the medication inconsistently. There are huge sums of money at stake in getting people to take their drugs as prescribed. In a 2008 article published in the drug industry marketing journal Pharma Marketing News titled "Moving The Needle on Adherence: Highlights from the 7th Annual Patient Compliance, Adherence and Persistency," ‎it was estimated that an 18% improvement in compliance would translate into increased revenues of approximately $8000 per patient a year.

What are the unintended, adverse health effects of this technology? Has it been sufficiently safety-tested? These are questions that remain largely unanswered, but have already been raised in connection with other proposed RFID technologies intended to be implanted within the human body.

The Bill & Melinda Gates Foundation, which has recently come under criticism for their financial support of GMO agriculture, 'edible' and 'flying' vaccines, pesticide-laden traditional scarves, and other questionable technological interventions ostensibly to reduce suffering, are also prominently figured partners on the Proteus Digital Health website.

The European Union was the first to approve Proteus' system device in 2010, indicating the market for the technology is global.
