Khushi baby

Case study curated Yizhen Li, Yixin Li and Junhui Jiang

Khushi Baby is a wearable platform to bridge the world’s immunization gap. 

Project description: “We’ve integrated mobile health, wearable NFC technology and cloud computing to produce a complete platform to bridge world’s maternal and child health gap; our goal is to be the digital key, marrying tradition with technology, to connect the last mile to health and social services.” (from: WHAT WE DO)

Khushi baby means happy baby in English. This is a project started by a Yale student’s team. This project already protected thousands of babies in Northern India from disease. Every year, approximately 1.5 million children die around the world from diseases that could be easily prevented through the use of a vaccination. As it stands currently, many
non-governmental agencies in the developing world keep immunization data in paper log books, which are cumbersome, often outdated and tough to search through to find a particular child’s information. Coupled with the frequency of families losing their medical documents, it means community health care workers don’t know which vaccines to bring with them to immunization camps.

Khushi baby necklace is inexpensive, less than one dollar, it is unpowered, locally available, and works with no need connectivity.

Using smartphones to scan the necklaces which infants are wearing, through the Khushi Baby App, health workers can check infant’s complete medical history and vaccination records.

  • Low cost (if patients do not have phones, health workers have smartphones can also check information through Khushi Baby App)
  • Reduce human (health workers) resources
  • Khushi Baby App can store nearly complete patients’ information
  • Decrease children die around the world from diseases that could be easily prevented through the use of a vaccination.

Through the Wearables for Good Challenge, UNICEF, ARM and frog, set out to demonstrate how wearable technology can be used to solve some of the most pressing challenges facing children. We put out a global call to action to developers, designers, community partners and problem-solvers to join us in this challenge. We attracted over 1,800 registrants from 65 countries, which resulted in 250 entries from 46 countries around the world. Accompanied by a Use Case Handbook created by UNICEF and frog, the challenge invited the global design, technology, and business industries, as well as social communities and universities, to identify and develop solutions for areas where wearable devices can generate tremendous social good. Announced in November 2015, the two winners of the challenge – Khushi Baby and SoaPen – successfully demonstrated how wearable technology can address some of the fundamental challenges children face in the areas of immunization and water and sanitation, respectively.
