@Penmate

PROPOSAL-2 Could you clarify whether the priority is on wearable comfort and form factor first, or on sensor fidelity and biomarker accuracy for the initial prototype? I can design and prototype a thin, skin-friendly patch that integrates sweat onset detection, moisture-level measurement, and real-time monitoring of selected biomarkers including cortisol and electrolytes, providing pH and metabolite data streams in a format readable by phone or PC; the workflow will include sensor selection, calibration, and data processing algorithms, plus recommendations for materials and attachment method to ensure comfort during wear, and I’d like to know if you prefer a flexible patch for multiple skin types or a single-size design to start with.

@tetianam8

⭐⭐⭐⭐⭐ This is an interesting project, and you’re right to frame it as a research / wellness prototype rather than a medical device — that makes the technical choices much more realistic and achievable. I’ve worked on sensor-driven wearables and low-noise bio-sensing systems, and I’d approach this patch as a clean, modular prototype that gives you usable, quantified signals without overpromising on biology. My plan would be: Detect sweat onset and relative sweat rate using impedance/moisture sensing combined with simple microfluidic guidance. Measure electrolytes (Na⁺/K⁺), pH, and a metabolite like lactate using proven electrochemical methods. Include a cortisol sensor designed for trend tracking, not diagnosis, with clear calibration limits documented. Design thin, flexible electronics with BLE so data streams cleanly to a phone or PC in real time (raw + processed values). Provide firmware, schematics, PCB/flex layout, BOM, and a repeatable calibration/testing procedure. You’ll get a working prototype that produces real data, plus honest documentation about accuracy, drift, and biological constraints — no black boxes. I focus on designs that are comfortable to wear, electrically stable, and easy to iterate. Happy to discuss wear duration, sampling rates, and how experimental you want the hormone sensing to be.

@dragomira2

Hello swimtrack, Thank you for sharing this exciting project. I’m genuinely enthusiastic about the challenge of developing a skin patch capable of detecting sweat onset, hydration proxies, and a range of sweat biomarkers, including hormone detection. With a background in biomedical engineering and hands-on experience in prototyping wearable biosensors, I understand the complexities of integrating multi-modal sensing in a thin, comfortable patch. My work has included development of electrochemical and impedance-based sensors for real-time metabolite and electrolyte detection, as well as embedded system design for low-power, skin-worn devices. I am also skilled in computational fluid dynamics, which will help optimize the microfluidic aspects for reliable sweat sampling. For this prototype, I propose a modular patch combining flexible microfluidics with miniaturized sensor arrays for pH, electrolytes, metabolites, and cortisol (using aptamer or immunosensing techniques). Signal processing on a compact embedded system will provide calibrated outputs, and I will ensure Bluetooth connectivity for seamless data streaming to phones or PCs. Data visualization and analysis will be presented in a research-focused, non-clinical format, supporting your intended use. I’m committed to delivering a robust, research-grade prototype that aligns with wellness applications, and I look forward to collaborating with you to bring this innovative concept to life. Please let me know if you’d like to discuss specific technical preferences or use-case requirements in more detail.
