How Smart Shirts Are Replacing Chest Straps for Heart Rate

Lucas and Luna explore the emerging world of textile-based biosensors — smart shirts, sports bras, and compression wear that replace traditional chest straps and armbands. They focus on a specific case: the shift from adhesive electrodes and elastic bands to conductive yarns woven into everyday athletic wear. Key numbers include the growth of the smart fabrics market, currently at $175 million in 2026, projected to reach $2.3 billion by 2031. They discuss how companies like Under Armour and Sensoria are embedding dry electrodes and ECG-grade sensors into garments, and why accuracy still lags behind medical-grade chest straps by about 3-5%. The conversation also touches on the trade-off between convenience and precision, and how the next generation of smart textiles could change cardiac monitoring for athletes and patients alike. #SmartShirts #TextileBiosensors #WearableTech #HeartRateMonitoring #ECG #SmartFabrics #UnderArmour #Sensoria #BiometricClothing #AthleticWear #HealthTech #MedicalDevices #ConductiveYarn #DryElectrodes #WearableECG #FitnessTracking #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo
