Market Analysts
“Lister technology provides the first
measurable, scientific method of diaper
changing. It should be attractive to all major
manufacturers”
Alan Perlman, Marketing Opinion Letter, formerly of Arthur D.
Little
“The user benefits provided by the predictive
indicators make powerful claims for both adult
and infant markets.”
John Starr, John R. Starr Inc.
The pH Problem with Diapers
Exposure to elevated pH is the underlying
cause of skin degradation and infections in
diapered area
Diapered skin pH cannot be controlled by
the diaper manufacturer
skin degradation & proclivity to infections
are idiosyncratic & idiopathological
pH in diapered area rises variably
according to the individual wearer
pH increases at an accelerating rate
Dynamics of pH in Diapers
Known: pH will rise as long as diaper is
worn.
Known: pH will become increasingly
deleterious to wearer.
Unknown: what is pH at any given
time, and how fast is it rising, and when
will it reach the problem stage?
Usage Problem with Diapers
Caregivers don’t know when to change because
they have no way to know pH status =
ineffective & inefficient care
Changing too frequently
Wastes time & money
Changing too infrequently
promotes costly skin degradation / infections /
malodors / discomfort
This Technology Solves the Problem
Predictive pH indicators provide advance
warning when the diaper/pad will need to be
changed to prevent and reduce skin damage
and infections
Time to change:
Not too soon …..
Not too late …..
Just in time!
Optimizes usage, costs and prevention

What is pH?
Measure of acidity or alkalinity of a liquid
pH = - log (activity of hydrogen ions)
Activity ~ concentration
pH range usually taken as 0 to 14
Acidic
0
Neutral
7
Alkaline
14
Wetness Enables Smart Sensors?
pH is measurable if liquid is present
Conductivity is measurable if liquid is
present
Certain compounds change color with a
change in hydration due to liquid
Wetness sensors vs. pH sensors
Wetness sensors are binary
Detect only wet/dry state
Not necessarily chemical changes
Not multiple changes
“Smart” pH sensors monitor chemical changes
that affect skin health
Follow change in pH with time
Predict remaining safe life of
absorbent article
Types of pH sensors
Chemical sensors
Color of dye changes with pH
No intrinsic electrical signal
Electrochemical sensors
Electrochemical potential changes with pH
Voltage output gives predictive capability
Electrode Requirements for

Implications of Sensor Response
Onset of wetness was immediately detected
through pH measurement
pH monitored was the most alkaline (highest)
value along the sensor
Response of sensor was a novel and critical
result
for detecting “hot” pH zones
for predicting when to change a diaper

Parent or daycare providers do not know
when to change...
