Smart technology is addressing personal safety in other ways and college campuses are embracing a more basic form of this tech.

Earlier this year we wrote about the Guardian Angel, a pendant that alerts emergency contacts whenever wearers feel unsafe, created by JWT Singapore. Smart technology is addressing personal safety in other ways too. The Defender is a smart pepper spray that works in tandem with a mobile app, taking a picture of an attacker while contacting authorities. It’s in the final week of an Indiegogo campaign that has well exceeded its goal. Similarly, First Sign has crowdfunded a smart hairclip that detects physical assault, records the evidence and sends for help.

Meanwhile, college campuses are embracing a more basic form of this tech, encouraging students to download apps like Rave Guardian and Circle of 6, which enable a chosen network to monitor a student’s GPS location during a night out. In a different vein, students at North Carolina State University made headlines last week for their Undercover Nail Polish, which changes color in the presence of “date rape drugs.”
