Wearable technology has the potential to revolutionize healthcare by providing real-time health monitoring and analysis through devices worn directly on the body. Examples discussed include an epilepsy tracker T-shirt that monitors seizures and sends data to a doctor's app, a smart bra that can detect breast cancer tumors through thermal sensors, and a temporary tattoo called a Bio Stamp that monitors multiple vital signs. These technologies promise benefits like lower healthcare costs, improved accuracy and timeliness of data, and greater convenience for both patients and doctors through mobile access to cloud-based health information. However, questions remain around how wearable devices could impact personal privacy and if privacy risks are justified by the healthcare benefits.
