INVIZA® HEALTH generates power from piezoelectric, mechanical energy harvesting to enable its health and fitness sensor suite. In addition, by using multiple sensor's output data via software, i.e. "sensor fusion" INVIZA has learned to lower power overall sensor and electronics power consumption while simultaneously increasing health and fitness measured parameter's accuracy. This leads to the insole tracker's battery staying 100% full while the user obtains the most accurate data.

Aluminum nitride “AlN” -vs- Lead-based “PZT”
Mechanical energy generation
• Lead-based PZT produces energy U = 2-miliJoules (mJ) per step  U = 2-Joules per 1,000 steps
• AlN produces U = 4X to 20X as compared to PZT depending upon scandium (Sc) doping level*
– Two (2) AlN-based EH w/ Sc @ 0% doping  U = 4X  4 x (2-Joules) = 8-Joules in 1,000 steps
– Two (2) AlN-based EH w/ Sc @ 26% doping  U = 20X  20 x (2-Joules) = 40-Joules in 1,000 steps

What is sensor fusion and why is it important?
 Sensor fusion is combining 2 or more sensor’s data to obtain a
better result through software algorithms
8
 foot swing + foot pressure  step count  accurate result
low power + passive power  low energy usage!!
• watch/ arm swing measured via 3-axis accelerometer  step count  inaccurate result
• insole/ foot swing measured via 3-axis accelerometer  step count  inaccurate result
Example  step count:

Second example – SmartCalories™
• Top 7 smart watches on market are 27-93% inaccurate (Stanford University)
 Uses only pulse-ox / heart rate to calculate burned calories
9
• INVIZA HEALTH is < 5% inaccurate (lower body burned calories only):
 Pulse-ox / heart rate to calculate background burned calories (living calories)
plus
 Accelerometer A / motion in X, Y and Z to calculate mechanical power
Pmechanical = force Fmechanical x speed s = (mass M x AX,Y, or Z) x (AX,Y, or Z x time t)
Then, convert from Pmechanical to Phuman using known conversion factor to calories

Semi rigid orthotic arch support foot cushion alignment shock absorber insole

Insole designed for
walking and comfort
Materials
1. Fabric w/ anti-bacterial agent
2. Ethylene vinyl acetate (EVA)
3. Polypropylene (PP)
4. Polyurethane (PU)
Using EVA as the footbed in an insole has now become common practice due to the
supportive and comforting nature of the material. It is a foam-based material, lending
itself naturally to supportive properties of an insole. EVA insoles are ideal as a shock-
absorber, protecting the foot from impact with the ground and helping to protect the
joints and ligaments in the foot. This rubber-like plastic has a high heat and cold
resistance on top of being particularly durable.

Recommended sensor priority and sampling rates
1. 6-axis accelerometer/gyroscope  step count and
motion-mass-based burned calorie calculations
– every 3-seconds
2. IR temperature sensor  body temperature
– 2X per day morning and evening, and on demand
3. pulse-ox (red/IR LED)  blood oxygen saturation
– 1X per day, and on demand
4. pulse-ox (green LED)  heart rate  background “living” burned calorie calculations
– every 6-minutes
5. piezo-force sensors  weight trends  overall health, e.g., rapidly increasing weight
could indicate edema or pulmonary edema, which the latter is an early indicator of
congestive heart failure (CHF)
– every 1-hour (patent-pending design)

Summary
 Energy generated from harvesting must be greater than what is
consumed
– Choose low power sensors wisely
– Choose low BLE transmission and
sensor sampling rates and with
reasonable duty-cycles
– Choose AlN over PZT for piezoelectric mechanical energy harvesting
to produce significantly greater energy per step
 Use sensor fusion to reduce power consumption and obtain highly
accurate results
