Li-Chang Kuo’s Caring Technology
Written by Peter Li-Chang Kuo
(Chinese)
“Caring Technology” was one of the five major
industries we advocated for in the 1980s as part of our Socially Responsible
Investment (SRI) initiatives. The aim was to help the elderly live healthily,
happily, and with dignity, their faces glowing with smiles like the sun—thus
the term “Caring Technology.”
According
to
The
World Health Organization defines a society with 14% of its population aged 65 and
over as an “aged society,” and 20% as a “super-aged society.”
Humans
are upright vertebrates. Our feet bear the entire body’s weight throughout the
day, while everyday burdens disrupt the natural flow of energy and blood—thus
the saying: “When a person ages, their feet fail first.”
Some even disrespectfully refer to elders as “useless
old fail.”
In
1982, I suffered a coup that stripped me of many things —including an unborn
child— and left me penniless after their violence. I left
Every
day, I would run 5,000 meters at the school playground across the street, do
stunts on the parallel bars, followed by dozens of "small wheel exercises" on the horizontal bar.
One day, after sitting down, I had a sudden inspiration: I drew an electronic
circuit that converted sine waves into "sawtooth
waves," which powered a transformer connected to conductive rubber
pads applied to joints and wrists. When electrified, they stimulated the
muscles — thus creating an electronic massager, which I named “MASU” (short for Massage Unit).
I
built it the size of three stacked books, producing 200 units at a time, which
became Master Kuo’s signature gift—sent to
I
asked myself: “How many contributions have I made to
the world that I’ve already forgotten?”
Main Components of
MASU:
1) 555 Timer IC ×1
2) Small Inductor (100μH to
1mH range)
3) Fast Diode (e.g., 1N4148)
4) Storage Capacitor (around
10μF to 100μF)
5) Variable Resistor VR
(10kΩ or 50kΩ)
6) Switch, AV Conectors
7) 9V Battery Clip and DC
connector
8) Outer Casing (approx. 5 ×
16 ×
9) Designed Mini Transformer
for higher voltage output
After
intense workouts, using the MASU for electrotherapy left me energized and full
of vitality. Besides bringing Barbie dolls back to life, I also taught classes

As
upright creatures, humans rely on their feet for support. Thus, foot health is
fundamental to overall well-being in an aging society. I once wrote an entire
book "On Meridian Theory," and
together with the MASU I gifted, students could take care of their own joints
and ankles at home.
In
communities, we often see foreign caregivers pushing elders in wheelchairs—proving
that “when a person ages, their feet fail first”
is no exaggeration. In my SRI publication on "Caring
Technology," I emphasized foot care, starting with diet and weight
control, and maintaining daily physical activity.
Overweight
individuals increase the burden on their feet—a major concern for the elderly.
It is said that each kilogram of body weight consumes about 30 kcal per day
just to maintain basic metabolism such as heartbeat and breathing. Therefore, a
proper diet that provides essential nutrients is crucial. The medical community
has confirmed that: “1,000 kcal per day is key for weight loss.”
Diet
control must be combined with appropriate exercise to be effective. When
overweight, one must not only manage food intake but also exercise to lose fat
— though never in a starved state, which harms health. WHO guidelines for
elderly nutrition include:
1) Moderate calorie intake
2) Fat under 15% (oils:
corn, sesame, peanut)
3) Protein at 15%
4) Zinc (micronutrient that
boosts immunity, metabolism—found in beef, peanuts, brown rice, seafood)
5) Fiber (at least 16–
6) Salt (<
7) Cholesterol (<
Exercise
not only burns calories but also increases muscle mass, boosting metabolism.
More muscle means a higher basal metabolic rate. Elderly individuals, due to
muscle loss, often see a decline in metabolism. Without adjusting diet
accordingly, they are prone to gain weight, which burdens "feet, joints, spine, cardiovascular system, organs, and
brain." Therefore, MASU is especially beneficial for elderly
at-home care.
When
an elderly person already has foot problems, they can no longer benefit from
exercise. I’ve witnessed the power of acupuncture—once, a needle inserted into
the cervical spine paralyzed a man instantly. That inspired me to urgently
develop the MASU—a kind of electronic acupuncture device, without needles to
invade the body, using “sawtooth wave”
stimulation via conductive rubber pads to activate joints.
After
leaving
One
morning during hospitalization, a nurse woke me to swallow a “one-inch-long black test pill.” I immediately felt
like my body was being stung by ten thousand ants, my consciousness floating to
the ceiling. I almost died.
Though
saved, I was into the hospital by walking, but was carried out. A 10-meter walk
now took me ten minutes—and I began a “difficult
rehabilitation journey.” Later, I searched the hospital, but that nurse
was never found.
During
rehab, I delved into anatomy books about "organs,
blood vessels, spine, meridians, and acupuncture points." I
discovered the human body has over 100 billion blood vessels. Scientists
estimate that if laid end to end, the total blood vessel length of an adult
would reach
Life
depends on breathing and blood circulation. The heart pumps blood through
large, medium, and small arteries into capillaries, then returns via veins to
the heart. A full circulation takes only 20 seconds. That means 180 cycles per
hour, 1,576,800 per year, and over "126 million
cycles" in an 80-year lifespan.
Scientifically,
the human body consists of:
1) Water (60%)
2) Carbon (18%)
3) Nitrogen (3%)
4) Calcium (1.5%)
5) Phosphorus (1%), plus
trace minerals like iron, copper, zinc, boron, and silicon.
These
elements may seem worthless individually, but when assembled into a living
being, they are priceless.
I
reviewed the “Universal Drug Manual” and found
that every drug has side effects. No wonder my condition worsened with
medication. I immediately threw away all pharmaceuticals—both western and
traditional — and did a reset. All medications were discarded, despite the
doctors warning me never to stop taking them for a year.
I
started with plain water, gave up supplements, and ate only bland mantou
(steamed buns). I lived on two teaspoons of royal jelly daily. Later, I added
Atractylodes (Bai Zhu) from the "Compendium of
Materia Medica" to strengthen my stomach.
After
using the MASU for physical therapy, I reduced the time to walk 10 meters from
10 minutes to 1 minute, and eventually to 10 seconds. I then developed a larger
version called the "Puluo Machine" —
a blood circulation device using purely physical methods to circulate blood,
activate meridians, and strengthen muscles and joints.
I
once again full of energy to travel around, promoting a better future for the
next generation, personally funding “Science & the
Future” seminars, and presenting my ideas for rebuilding the global
economy at APEC CEO Summit.
Conclusion
From
personal rehabilitation experience, I found that as long as one can breathe
fresh air and avoid overexertion, even a simple breakfast of one unsweetened
bun, a modest lunchbox, and a bowl of noodles for dinner is enough to live
well.
The
Creator endowed the human body with self-healing power. As long as the immune
system is intact and blood flows freely, one can remain healthy. But with
aging, that self-healing weakens. Environmental pollution, climate extremes,
and social challenges further harm our bodies.
When
the body is too weak to circulate blood on its own, exercise becomes
impossible. Seeing my own contributions to “Caring
Technology” still in use in rehab clinics today, I believe that if I
ever have the time, I would love to restore the “MASU”
and “Puluo Machine” for public benefit — they
could greatly help our aging population.
