Corey Menscher, a student at New York University's ITP program, created KickBee. The project is a wearable device that pregnant women wear as it senses the baby's kicks, which then get turned into messages. The wearable device is made of a stretchable band, sensors, and an Arduino Mini microcontroller that sends signals to an accompanying Java application wirelessly via Bluetooth. The signals then get translated into a message that is automatically posted on the microblogging site, Twitter.
What I like about this project is the usefulness of the concept and the extension of the garment into additional products such as Twitter. By connecting it to Twitter, the device becomes an ecosystem that senses and communicates via its own network.
