What are some examples of problems that might be addressed?

Below are some examples of smart city initiatives that may give you some inspiration:

  • A smart navigation glove for motorcyclists embedded with Bluetooth technology connected to mobile phone navigation apps help reduce road accidents caused by the use of mobile phones by motorcyclists. This innovative solution was developed by the 2019-20 Grand Challenge winners.
  • A Korean city implemented smart water meters, which today double functions as a social health alert: family of people who haven’t used water in two days are sent an alert.
  • The blood bank in Amsterdam uses smart heat exchange systems to ‘store’ the cold from their water system in the winter, in order to keep blood cool in summer.
  • Melbourne can get hot in summer and its tree health sensors measure the water needs and co2 conversion of the trees, the city council maintain the foliage that protects the city.
  • A hamburger chain implemented smart gas meters, to warn them when a bottle was about to go empty, but they also found that they hadn’t been receiving full gas tanks all the while, generating significant savings.
