For me, living in NYC means that my nightly commute between the train and my apartment is often fraught with concern for my safety. 

I designed a wearable tech piece with a piezo buzzer and conductive tape that sets off an alarm when the wearer triggers the alarm by closing the circuit with a copper ring; any metallic/conductive trigger would work.
