The document discusses how IoT can transform healthcare by enabling intelligent interactivity between patients and healthcare providers. IoT uses technologies like sensors, RFID tags, and cloud computing to connect devices and apps, allowing doctors to remotely diagnose, monitor, and track patient vital statistics and medical information. Examples mentioned include wearable devices that measure things like brainwaves, blood pressure, and glucose levels. IoT in healthcare aims to gather rich health data from patients to improve care and quality of life while minimizing human error through continuous remote monitoring and alert systems.
