Tracking your students
Wearable technology isn't always necessary a plus. Some schools, including the John Jay High School have implemented badges that contain RFID tracking chips -- so a school is always able to know where they are.
Some argue that the chips are useful in cutting down the rates of students skipping school, whereas critics believe that such "smart IDs" are an invasion of privacy.

A bra primed to shock your attacker
When the safety of women is a severe issue in countries including India, some citizens turn to tech for solutions.
Manisha Mohan, an aeronautical engineering student at SRM University in Chennai, has developed a prototype bra which is able to "shock" attackers. After being groped, pressure sensors are activated and cause the bra to deliver an electric shock of 3800kv. The prototype is also able to send a text message to police with GPS coordinates.
Describing her motive behind the project (.pdf), the student said that "Lawmakers take ages to come up with just laws and even after that, women are unsafe. Hence, we have initiated the idea of self‐defense which protects women from domestic, social and workplace harassment."
With Glastonbury Festival goers in mind, Orange and renewable energy experts GotWind have unveiled a prototype for thermoelectric wellies that can chanrge your smartphone on the go.
The Orange Power Wellies are equipped with "power generating soles" that convert heat from your feet into an electric current. Slot your mobile into its pouch and this energy is used to charge your device -- handy if you're partying in a field without a power source nearby.
