Hi, I’m Muhammad Awais, excited to help you design a thin, comfy skin patch that detects sweat onset and moisture, measures hormones like cortisol, electrolytes, metabolites and pH, and streams data to phone/PC. I will use flexible microfluidics, low-power sensors, and a compact embedded system to deliver a reproducible signal, calibration options, and a clear data interface for wellness research. I’ll provide hardware prototypes, sensor integration, firmware, data pipeline, calibration data, and a simple app/visualization. Deliverables include a proof-of-concept patch, circuit and PCB layouts, sensor calibration protocol, data stream with timestamped readings, and a demo dashboard. This is framed as a research/wellness prototype, not a diagnostic device, with clear limitations and safety notes. I propose a phased approach: requirements capture, hardware/sensor selection, enclosure design, firmware/app, validation, and documentation. I’ll tailor milestones, risk plan, and a practical timeline to your needs. What is the target patch size and thickness? What hormone marker should be prioritized (cortisol) and which other biomarkers? What calibration level is acceptable (per patch vs batch), and what data format is preferred for the data stream? Which platforms are required for the data viewer (iOS/Android/PC) and should it work offline? Any safety/regulatory constraints or disclaimers for a wellness prototype?

Hello, I understand you’re looking for a biomedical engineering and embedded systems expert to design and prototype a thin, comfortable skin patch capable of detecting sweat onset, moisture levels, and a set of sweat biomarkers including at least one hormone marker such as cortisol. I have extensive experience developing wearable biosensor prototypes, integrating microfluidics, electronics, and sensor arrays to provide real-time data streams that are compatible with phones and PCs. My approach ensures accurate detection of hydration, electrolytes, metabolites, and pH while maintaining user comfort and wearability. The design would incorporate miniaturized sensors and calibration algorithms to quantify sweat composition and provide reliable, interpretable signals. Data visualization and analysis pipelines can be built to output clear, actionable metrics for research or wellness purposes. I focus on rapid prototyping, iterative testing, and modular electronics integration, ensuring that the patch delivers both accurate biochemical readings and a seamless digital interface. By combining expertise in embedded systems, computational fluid dynamics, and biomedical engineering, I can deliver a functional prototype framed clearly as a research/wellness tool rather than a diagnostic device. The result will be a compact, reliable sweat monitoring patch with quantified outputs, real-time digital readouts, and clear documentation for further research or development. Thanks, Asif

@leonidye

Hi,I have seen your JD carefully. I can design and prototype a thin, comfortable sweat-sensing skin patch that detects sweat onset/moisture level and measures a panel of electrolytes, metabolites, pH, plus one hormone marker (e.g., cortisol) using research-grade electrochemical sensing (framed strictly for wellness/research, not diagnosis). The patch concept will combine a soft adhesive microfluidic layer (to route fresh sweat) with a flex/flex-rigid PCB hosting an analog front end for amperometric/potentiometric reads, plus a low-power BLE MCU for phone/PC data streaming. I’ll deliver quantified sensor signals, calibration routines (bench + on-body protocols where feasible), and a calibrated estimate of sweat rate/hydration proxy with clear uncertainty notes and limitations. Outputs include firmware + BLE data format, a simple mobile/desktop reader (or CSV/USB gateway), and dashboards/notebooks for visualization and analysis. Hardware deliverables cover schematics/PCB, BOM, assembly files, and prototype build guidance, along with a concise verification test plan (repeatability, drift, temperature effects, wear time, and comfort). Budget and timeline fit the range depending on whether the cortisol channel is implemented as an aptamer/immunosensor disposable electrode (recommended for stability) or a reusable research sensor approach.

Hello swimtrack, Thank you for sharing this exciting project. I understand you require a thin, skin-adherent patch capable of real-time sweat onset detection, hydration monitoring, and the quantification of sweat biomarkers—including at least one hormone (such as cortisol), electrolytes, metabolites, and pH—delivering calibrated digital signals to a mobile or PC interface. As a research/wellness prototype, accuracy and user comfort are critical, but the device need not meet medical diagnostic standards. My background in biomedical engineering, electronics, and sensor prototyping uniquely positions me to deliver this solution. I have developed wearable biosensors and data acquisition systems, integrating electrochemical and impedance-based sensors on flexible substrates. My experience spans microfluidics for sweat sampling, computational fluid dynamics for patch optimization, and embedded firmware for robust signal processing. I also have a proven track record designing Bluetooth-enabled devices with user-friendly data visualization and analysis pipelines. To address your requirements, I propose a modular approach: (1) Selection and integration of miniaturized sweat sensors (electrochemical and ion-selective) on a biocompatible, breathable patch; (2) Onboard signal processing and calibration to translate raw sensor data into meaningful metrics; (3) Wireless transmission of cleaned, structured data to a companion app or PC dashboard for real-time visualization. I will document all design steps and ensure the prototype is safe, comfortable, and ready for research or wellness use. I am excited by the potential impact of your project and look forward to collaborating on an innovative, practical prototype.
