Watch the Wanderers

Kenneth Shinozuka was 14 when he began working on a wearable device to monitor patient activity. The resulting SafeWander—consisting of a tiny button sensor worn by the patient, a gateway, and a mobile app—sends an alert to the caregiver’s mobile device when the sensor detects a change in the patient’s body position. US$199.

See the Beat

High schooler Suman Mulumedi was curious about what physicians do when heart murmurs are too quiet to be picked up by a stethoscope. So he created Steth IO, an elegant case that turns a smartphone into a stethoscope, bringing visualization to heart and lung sounds with precise digital filters. Device users can monitor their heart at home and send recordings directly to their physician for review. Steth IO is FDA-approved for clinicians and for patients with prescriptions. US$199.

Computer Science for All?

Does a student need to major in computer science in order to snag one of those high-paying jobs?

Computer science experience can boost a candidate’s chance of success in high-growth, high-paying careers in data analysis, engineering and manufacturing, design, marketing, and programming and IT areas, but most of those jobs do not require a computer science degree.

Apps: Young Developers with Smart Solutions

Turn your mobile device into a science lab, social savior, and school guide for the blind with apps from the under-20 crowd.



When University of Chile student Komal Dadlani became aware that many students in her country did not have the equipment to properly study science, she and two fellow students founded a company to do something about it. Lab4U develops apps such as Lab4Physics—which includes speedometer, accelerometer, and sonometer sensors—that turn smartphones and tablets into scientific tools so that any student with access to a phone can conduct research in the physical world. Free (Android, iOS, Microsoft Windows)

Sit With Us

six with us

Sixteen-year-old Natalie Hampton ate lunch alone every day in seventh grade and wanted to spare students from the loneliness and bullying such isolation can cause. So she developed Sit With Us, a social networking app that lets kids find a place to sit with the click of a button rather than facing an awkward walk through the lunchroom. The app also allows students to act as ambassadors, inviting others to join them and hosting open lunches that anyone can join. Free (Android, iOS)

Hello Navi


Navigating a school’s traffic jam between classes can be challenging for any student, but it’s especially hard for the visually impaired. A group of six grade-school girls in Los Fresnos, Texas, developed Hello Navi to address the problem. With Hello Navi, a mobility specialist can set up various paths between campus locations for a visually impaired student to use; the student then talks into the device to request help navigating to and from locations.
