Implantable sensors exist for a number of applications, having been used in animals for pet identification for many years. Other examples under development or seeking FDA approval are glucose detection for control of diabetes, blood pressure monitoring in people with recent cardiac arrest or risk of heart disease, and blood health. The most recently announced is implanted into animal brains with the long-term goal of enabling humans with paralysis to control machines with their minds. These implantable sensors have this in common: they self-contain what is needed to transmit information from inside your body without batteries and without wires. These are already shown to work; several are now seeking FDA approval. From the perspective of a patient, this is a Tricorder device, albeit one centered on an implantable micromachine sensor. If you or your doctor feel your health is at risk, I suspect you’d accept these inside your body. If your health feels not at risk however, this could be too invasive for your liking, and we’ll offer you something one level easier to accept.
Ingestible sensor chips are an idea a little easier for most people to swallow. Here are three examples. Camera pills, which pass through your digestive tract taking pictures and transmitting them out are available from Given Imaging. Available to your doctor, that is. You may have seen the commercials. But two other swallowable sensors are now on the scene. You can find the Internet movies of Lance Armstrong downing the CorTemp thermometer pill from HQInc. This pill travels through your digestive tract wirelessly transmitting your core body temperature. Useful for athletes today, and for those with occupational exposure to high temperatures. Again, this mimics a singly-capable Tricorder device where hand-held electronics receive wireless signals about the temperature inside your body. A third ingestible, a wireless sensor pill from Proteus Digital Health does something simple, but vitally important: it reports that you’ve swallowed it. This first offering from Proteus is a placebo, with silicon computer chip attached. This pill, coupled to a wearable patch, which is coupled to a smart phone has been discussed in an article here at Forbes/Singularity previously. When the pill hits your stomach, it transmits to your phone that you took the pill. Your phone then does whatever you would like with the data; informs your doctor, or informs a trustworthy caregiver. If Proteus is right, and these sensors become commonplace, exponential growth in digital medicine for compliance monitoring will require as much silicon wafer manufacturing as all computer chips use today. And your phone will be filled with information about when you took your medication.
With over 200 competitors,
expect to see many variants of wireless implantables, ingestibles, and intimate body contact sensor ideas introduced in the coming year.
