Smart bracelet can detect if wearer is attacked and call for help without the push of a button

A University of Alabama master's student has developed an unusual tool to combat sexual assault: a bracelet. The device monitors wearers' vital signs and can pick up on changes that would signal being under attack. The smart bracelet, still in the prototype stage, alerts a predetermined list of contacts and the police if it senses that the wearer is being harmed. Additionally, it emits a loud alarm and is equipped with red strobe lights meant to scare away the attacker or get the attention of others in the vicinity. Jayun Patel, a master's student at the University of Alabama, designed a smart bracelet that can alert the authorities if a wearer is attacked.
