GlucoSonic: The Worlds First Non-Invasive Ultrasonic Glucose Monitor That Actually Works
GlucoSonic is an experimental, non-invasive ultrasonic glucose prototype — exploring needle-free monitoring with real user research
A working, personally tested medical device built by a scientist who depends on it every day
My name is Dr. Michael Gavshin, PhD in Physics and Mathematics. I have spent more than 30 years working with piezoceramic materials, ultrasonic sensors, and high-precision acoustic measurement systems. I developed multiple patented lead-free piezoceramic materials, and built ultrasonic hardware used in aerospace, medical, and industrial technologies.
My engineering team and previous projects are available at: www.piezosolution.com But this project became personal when I was diagnosed with type 2 diabetes.
As a result of complications, two toes on my left foot were amputated. Doctors warned me clearly: If I fail to monitor glucose accurately and take insulin on time, the amputations will continue. I am at real risk of losing my legs. For decades, I had the scientific expertise to build a non-invasive glucose monitor — but I did not have a biological subject to perform long-term experiments on. Now I do.
The test subject is me. For more than 18 months, I’ve been wearing my own ultrasonic prototype 24/7, and validating it every day against FreeStyle Libre 3 and Accu-Chek Instant It has never failed. I invested my own personal savings into building the first fully working device — because my health depends on it. My mission now is simple: To give people the same safe, affordable, painless device that keeps me alive every day.

What Exists Today (December 2025)
A fully functional, daily-use, non-invasive ultrasonic glucose monitor
• Worn 24/7 on the upper ear cartilage (antihelix)
• A small MP3-player-like main unit with a built-in display
• A wired clip connects the ultrasonic transducers to the ear
• Bluetooth to Windows and Android
• iOS and Android apps already developed (graphs, alerts, history, CSV export)
• All data automatically saved to the mobile app
• Accuracy validated daily against FreeStyle Libre 3 and Accu-Chek Instant
• Runs on proprietary ultrasonic multi-path acoustic processing
• Protected by US Provisional Patent 63/795,453:
“Ultrasonic Glucose Monitoring Device with Temperature and Distance Compensation”
Filed by Michael Gavshin
This is not a concept.
This is not a simulation.
This is a real, working, laboratory-grade device used continuously by a diabetic patient — its inventor.
Why Only the Upper Ear Cartilage Works
Other companies spent tens of millions and decades developing earlobe sensors. The result: no stable 24/7 data.
Why?
The earlobe is soft tissue. It moves. It swells.
Ultrasound cannot remain stable there — physics simply doesn’t allow it. Between 2022–2023 I personally ran dozens of failed experiments on the earlobe. Only when I placed the sensor on the rigid antihelix cartilage did the system become perfectly stable.
Rigid cartilage =📌consistent acoustic path📌no swelling📌no motion artifacts📌rock-solid coupling 24/7, even during sleep
This is the breakthrough that makes GlucoSonic possible.
How It Works (Simple Explanation)
Your glucose level slightly changes the speed of sound in biological tissue.
GlucoSonic measures this through:
• Custom high-frequency piezoceramic transducers • Multi-path ultrasonic waveforms • Precision timing • Temperature compensation • Distance compensation • STM32 microcontrollers • Proprietary acoustic algorithms • Wireless communication with smartphones
The result: Real-time glucose values with zero needles and zero pain.
And unlike all existing CGM sensors:
✔ No needles
✔ No blood
✔ No sensors to replace
✔ Works for life
✔Mass-production cost ≈$20
This makes GlucoSonic the firsttruly affordable CGMin the world.
The Global Problem GlucoSonic Solves
The Global Problem GlucoSonic Solves
Diabetes is growing faster than any other chronic disease:
• 537 million people worldwide today
• 643 million expected by 2030
• Millions rely on CGMs every day
• Current CGMs cost $80–250/month
• Sensors fail, detach, cause skin irritation, require needles
GlucoSonic eliminates all of that.
A non-invasive, needle-free, ultra-low-cost monitor could transform diabetes care — especially for children, seniors, and low-income patients worldwide.
Why We Need Your Help Now
Why We Need Your Help Now
Everything foundational is already built.
Now we need to scale:
⭐ 120–150 research units
⭐ 120–150 research units
To begin multi-user testing immediately.
⭐ Miniaturization
⭐ Miniaturization
Into a single earbud-like unit with a built-in display and USB charging.
⭐ Large datasets
⭐ Large datasets
For regulatory submissions (FDA 510(k), EU MDR).
The prototype works flawlessly on one person — me.
Now it must work on hundreds.

Use of Funds (High-Level Breakdown)
Use of Funds (High-Level Breakdown)
• 40% — Hardware, transducers, miniaturization
• 25% — Multi-user research & datasets
• 20% — Software & cloud features
• 10% — Regulatory & documentation
• 5% — Campaign operations
Risks & Challenges
Risks & Challenges
All medical hardware faces challenges:
• Must be worn on upper ear cartilage only
• Large datasets required for certification
• Miniaturization expected to take 9–12 months
• Regulatory timelines vary by region
However:
The physics is already solved.
The prototype already works.
This is not a research idea — it is a finished, functioning device needing scale.
Final Message
Final Message
This is not a startup pitch.
This is not a theoretical medical gadget.
This is a real device that keeps me — a severe diabetic — alive every day.
And I want the world to have the same protection, without pain, without needles, without $200 monthly expenses.
Thank you for helping build a future where glucose monitoring is:
✔ painless
✔ affordable
✔ accurate
✔ lifelong
✔ and available to everyone
