1) Optics and sensing technologies are becoming more portable and miniaturized, allowing for new diagnostic tools.
2) Spectrometers, sensors, and add-ons are entering the consumer market and have potential diagnostic applications by analyzing things like optical absorption, Raman signals, and THz signals.
3) This could enable new portable devices that provide basic health insights by examining things like the eye, which can provide clues about systemic conditions.

The idea of elixir of life has
been around for thousands
of years but let’s face it we
are going to die!

Increasing average life span
• Physics of body (Repair and preserve)
– Mental balance
– Physical exercise
– Food
• (Chemistry) Sensors
– Diagnostics
• (Physics, Chemistry, Statistics) Sensors and Computers
– Treatment

Now why now?!
Electronics starting to
become portable
Optics starting to
become portable
1) Optics is now starting to become
cheaper and more portable through
new miniaturization techniques.
(Nanomaterials, nanoplasmonics,
etc.)
2) 3D printing and quicker and cheaper
prototyping
What are the recent discoveries that
can help us toward healthier, longer
lifespan?

Wave of spectrometers
• They were all there in the lab but now they are entering
consumer market!
– Optical absorption diagnostic
– Raman food analysis
– THz skin, cosmetics, breath

Example
• Just like super computers we still need the accurate lab spectrometers but
portable versions can be used limited applications.
• Raman spectrometer from lab to the key chain!

These are amazing advancements and technologies but be
careful with the claims; things take time to develop and
usually have limited capabilities at the beginning.
