15 year-old creates a 3D printed iPhone case that’s also a stethoscope

When high school student Suman Mulumudi got his hands on a 3D printer, he decided to make an iPhone case, but one which really stood out from the crowd. It’s not covered in bizarre shapes, it’s not compatible with Lego, and it doesn’t have an unusual picture burned into it. No, it does something not only useful, but also unique.

It’s called the Steth IO, and it’s a stethoscope for the smartphone generation. Slot an iPhone into the case, and thanks to a diaphragm on the back, low frequency sound is channeled through a network of tubes leading to the microphone. It can then hear, visualize, and record the sound of a heart beat. The final product is the result of several prototypes, and have led to Mulumudi forming his own company, called Stratoscientific, and submitting the Steth IO for FDA approval. Oh, did we mention he’s only 15 years-old?

The recording of heart beats this way is apparently a first.

So how did the Steth IO come about? According to a story on Mulumudi published on the 3D printing firm MakerBot’s website, his father is a cardiologist, so he’s no stranger to the medical world and the heart in particular. A student at The Lakeside School in Seattle – well-known for bringing Bill Gates and Paul Allen together – he says the first version of the case took around two weeks to design, and that previous experience with 3D printing made it the obvious choice for developing the prototype.

The Steth IO is the latest in a string of interesting 3D printed mobile accessories seen over the past year, and Makerbot’s Replicator Mini received our Best in Show award at CES this year. There’s no information on when the Steth IO will go on sale, or if it will be available to the general public.

This A.I. app converts any photo into 3D, no dual lenses required
LucidPix smartphone app

3D photos literally pop out of any newsfeed -- but sharing one requires a device with dual lenses or Dual Pixel technology. Not for much longer, however. LucidPix, teased during CES 2020, is an artificial intelligence app that takes photos that you’ve already snapped and converts them into 3D images.

LucidPix works by using contextual A.I. to identify the objects in the scene, and then generating a depth map. The app, Lucid says, was trained using hundreds of millions of photos over the past several years.

New iPhone SE and iPad Pro with 3D sensing tipped for early 2020 release
iPad Pro 2018

The Mac recently got some love in the form of the new 16-inch MacBook Pro— and the iPhone SE and iPad Pro may be next. According to a new report from Ming-Chi Kuo, a well-known Apple analyst, the next iPad Pro iteration will be released in the first half of 2020, alongside a new version of the iPhone SE. The news was first reported by MacRumors.

The new iPad Pro is expected to offer a number of upgrades over the current-generation model. Notably, the device will likely have a rear camera capable of 3D sensing, which will work through a time-of-flight camera sensor, which can measure the time it takes for light to bounce off of objects, then generating a 3D map of an environment.

iPhone rumor says 2019 models will make 3D Touch a thing of the past
best iphone 6s screen protectors 3d touch

Continued rumors suggest Apple may remove pressure-sensitive screens from the next generation of iPhone models, bringing about the end of 3D Touch. The latest hint this may happen comes from an industry report on revenue performance for manufacturers making the modules that enable 3D Touch, stating that although “Apple may remove 3D touch sensors from all 2019 iPhone devices,” sales for these companies may still grow.

Published by DigiTimes, which has a prolific but sometimes spotty history with leak and rumor accuracy, it’s not the first time we’ve heard about the current iPhones being the last hurrah for 3D Touch. Only the iPhone XS and XS Max have pressure-sensitive screens at the moment, with the iPhone XR already dismissing the feature, presumably in an effort to keep the cost down and to increase the screen-to-body ratio. But 3D Touch’s absence shows Apple does not consider it essential to operating iOS, as a pressure-sensitive feature at least, or a strong sales point.
