Every year, dozens of small children are forgotten in cars. Sometimes a parent remembers and rushes back to the car - but sometimes they don't get there in time to prevent the child suffering harm.
Seventeen-year-old Alissa Chavez has designed a car-seat alarm system to alert parents when they've left a child in the car. The system sounds an alarm on the car, on a key fob and on an app when the parent is 10 metres away from the car but there is still a child inside.
"I just thought it was a terrible tragedy that there could be a stop to," Alissa told As It Happens guest host Helen Mann.
She's been working on this idea since she was in grade eight. "It started as a science fair project," Alissa said.
Alissa has almost met her goal on Indiegogo
, the online crowd-funding website. She says she's going to use the funds to build a prototype and hopefully start manufacturing the device soon.
