hDrop OEM & Sensor Integration
Bring sweat analytics into the devices athletes already wear.
Sweat Sensor Embedded
hDrop develops reusable sweat-sensing technology designed to measure sweat rate, sodium loss, and hydration-related insights in real time. After years of development through our dedicated wearable platform, we are opening selected collaboration opportunities with companies interested in embedding sweat-sensing capabilities into future wearable products.
Our technology can be explored for integration into heart rate monitor chest straps, watches with skin-contact electrodes, armbands, connected performance wearables, and ring-style devices with appropriate electrode contact.

Why Sweat Sensing?
Sweat is the next performance biosignal
Athletes already rely on heart rate, HRV, power, pace, temperature, and sleep data to guide training and performance. But hydration remains one of the most important physiological variables that is still largely estimated manually.
Sweat contains valuable information about fluid loss, sodium loss, and individual hydration needs. hDrop’s goal is to make this data accessible in real time and in the devices athletes already use.
With embedded sweat sensing, wearable companies can add a new layer of performance intelligence:
- Real-time sweat rate estimation
- Sodium loss insights
- Personalized hydration guidance
- Environmental and intensity-based sweat analysis
- Training and race-day hydration planning
- Post-workout fluid and electrolyte review
Integration Opportunities
Built for future wearable integration
hDrop is exploring OEM and strategic partnerships with companies developing the next generation of sports, health, and performance wearables.
Potential integration formats include:
Heart Rate Monitor Chest Straps
Chest straps are one of the most promising paths for embedded sweat sensing. They already provide stable skin contact, athlete acceptance, electronics, battery, wireless communication, and a strong performance-focused use case.
hDrop can explore sweat-sensing integration into HRM-style devices through custom electrode layouts, calibration, firmware support, and hydration analytics.


Watches with ECG or Skin-Contact Electrodes
Smartwatches and sport watches increasingly include electrical contact points for ECG or other bioelectrical measurements. These skin-contact surfaces may create future opportunities for sweat-sensing integration when combined with proper electrode design, placement, calibration, and signal processing.
hDrop can work with partners to evaluate whether their existing electrode architecture or future hardware design can support sweat-related measurements.
Wearables with ECG Electrodes
Wearables that already include skin-contact electrodes may be candidates for hDrop’s sweat-sensing technology. This includes performance monitors, health wearables, medical-adjacent devices, smart straps, and other connected products with direct skin interface.
hDrop can support early feasibility evaluation, electrode customization, calibration methods, and signal-processing strategies.


Rings with Skin-Contact Electrodes
Ring-style wearables present unique challenges due to size, sweat availability, motion, skin contact, and power limitations. However, rings with appropriate electrode contact may offer future opportunities for hydration or sweat-related sensing.
hDrop is open to feasibility discussions with companies developing ring-based devices and advanced skin-contact sensing platforms.
Calibration & Customization
Calibrated for the target form factor
Sweat sensing is highly dependent on placement, electrode design, skin contact, materials, motion, sweat availability, environmental conditions, and individual physiology. For that reason, hDrop approaches OEM integration as a calibrated and customized process.
We can work with partners to evaluate:
- Target wearable form factor
- Electrode geometry and placement
- Skin-contact materials
- Sweat exposure and flow
- Motion and artifact reduction
- Temperature and environmental compensation
- Device-specific calibration needs
- Processed output requirements
- User experience and data presentation
Each integration pathway is evaluated based on the partner’s hardware, intended use case, and desired level of sweat analytics.
Partnership Models
