E-cast: Make sense of it all - Discover wearable patches with secure, contactless NFC

Summary: Medical or Health and Fitness patches allow patients to monitor vital data on their own and share data securely to remote healthcare centers for analysis and instruction. The highly integrated ultra-low-power RF430FRL15xH system-on-chip enables the development of disposable patches that sense temperature, hydration and more for either battery-supported data logging in FRAM or on-the-spot, passive measurement using RF energy harvested from an NFC-enabled phone.
