# Hiyd Launches Invisible Health Tracker for Traditional Watches A slim microsuction sensor enables health monitoring without replacing your favorite timepiece. - **Source:** [TechCrunch](https://techcrunch.com) - **Published:** 2026-10-14 - **Topic:** [Product Management](https://brifing.si/c/product) - **Original article:** - **On Brifing:** https://brifing.si/s/4f604849-4ab9-47ff-8164-f8e8db519cf3 ## Invisible Health Tracking Concept Hiyd introduces a slim sensor disc designed to attach directly to the back of existing watches. Founder Salah Batroukh aims to eliminate the trade-off between fashion and functionality. By creating an invisible ecosystem, the company allows users to maintain their personal style while accessing advanced biometric data through a non-intrusive hardware solution. ## Microsuction Attachment Technology The device utilizes microsuction, a textured silicone material with tiny pockets that create a vacuum effect. This 0.3 mm thin sheet secures the sensor without magnets or adhesives, preventing residue or mechanical interference. This manufacturing process ensures the sensor remains flush against the watch case while allowing for easy removal when needed. ## Biometric Data Collection Capabilities Measuring 2.7 mm in thickness and weighing 7 grams, the sensor tracks heart rate, heart rate variability, and sleep staging. It also estimates VO2 max and calories burned, syncing all collected metrics to a dedicated iOS or Android application. The hardware provides comprehensive health insights comparable to standard industry wearable devices. ## AI Training and Heuristics The engineering team trains their AI models by filming themselves performing various physical activities. By labeling these specific datasets, the system performs rapid heuristic analysis to distinguish between walking, jogging, and running. This data-driven approach allows the software to interpret complex movement patterns and provide accurate, personalized feedback to the end user. ## Nutrition and Lifestyle Insights The companion app focuses on correlating eating habits with sleep quality and workout performance rather than simple calorie counting. It provides actionable insights, such as identifying how late-night workouts or sugar intake affect deep sleep cycles. This personalized analysis helps users understand the direct impact of their daily lifestyle choices on health. ## Founding Team and Vision Founder Salah Batroukh, a former manufacturing design engineer at Apple, leads the startup alongside CTO Omar Shakir and head of software Mahamad Charawi. The team prioritizes customer-centric design over corporate branding constraints. Their collective experience in mechanical engineering and software development drives the product's focus on seamless integration with existing consumer accessories. ## Market Launch and Traction Hiyd is competing as one of the top 20 companies at the Startup Battlefield during TechCrunch Disrupt. The company plans to launch a Kickstarter campaign in November to scale production. Currently, over 16,000 individuals have already made deposits to secure their first units, demonstrating significant early consumer interest in the product. ## Strategic Industry Positioning The emergence of Hiyd highlights a shift toward modular, non-intrusive wearable technology. By focusing on hardware that complements rather than replaces traditional watches, the company targets a specific niche of watch enthusiasts. This strategy challenges the dominance of bulky fitness trackers by prioritizing aesthetic preservation alongside high-fidelity biometric data collection and analysis. ## Sources covering this story - https://techcrunch.com/2026/10/14/hiyd-is-a-health-tracker-that-attaches-to-the-watch-you-already-wear/ — --- _Summary written by Brifing from the original reporting.
