To see how far technology is taking medicine, contrast the AliveCor iPhone ECG (watch video) to traditional electrocardiogram (ECG or EKG) machines that cost upwards of $10,000. They both record electrical activity of the heart for analysis, but the iPhone app is portable and cheap and no longer constrained to clinical settings.
AliveCor will demonstrate their iPhone app next week at the Consumer Electronics Show, which I will cover remotely.
Smartphones faster than mainframe computers
Because of Moore’s Law, which describes the exponential doubling of processor speed & memory, today’s smartphone is now 5,000 times faster than a 1970’s era mainframe computer that once cost 11,000 times more, required liquid cooling & large computer rooms, and was thus shared by hundreds or thousands of users simultaneously. Unlike the mainframe, smartphones are portable, personal, and have sensors for microphone, camera, accelerometer, gyroscope, compass, proximity detector, and now ECG/EKG sensors.
Smartphones are Smaller & Cheaper too
For more perspective, compare the physical size of the magnetic disc storage of IBM’s 3330 drives in 1972 (each drive holds 200 MB) and the company’s first disc drive (from its circa-1956 305 RAMAC supercomputer), which weighed over a ton and stored just 5 MB of data.
Next, extrapolate Moore’s Law and notice that:
- By 2013, a supercomputer will have the reasoning and processing capacity of the Human Brain;
- By 2023, a $1,000 home computer will have that power, and by 2037, a $0.01 embedded computer will; AND…
- By 2049, a $1,000 computer will have the power of the human RACE, and by 2059, a $0.01 computer will.
So, given these trends and the availability of wireless networks, powerful smartphones, and medical and environmental sensors, the stage is set for health innovation in the next few years like we’ve not seen in the history of mankind.
