Oh, gadget! The Stemoscope stethoscope

 Copyright © Françoise Herrmann

For a modest sum, you might purchase your own personal Stemoscope wireless stethoscope. No prescription or license required. According to UK medical student Youtube review, the Stemoscope is probably not medical-grade, simply because of the costs and red tape, associated with obtaining medical-device clearance (Burton, 2019; Ollie Burton). A comment, which suggests, together with the website’s M.D. review, that the device is powerful enough to pick up body sounds. However, this also means that the Stemoscope is a gadget that has not been cleared by the Food & Drug Administration (FDA) in the USA, or equivalent agency elsewhereexcept perhaps in China where the Stemoscope was apparently used, on an emergency basis, as a monitoring and safe auscultation device, during the height of the COVID-19 pandemic, in Wuhan (Stemoscope blog; Newscast). Emergency use, considering that. the use of classic stethoscopes with tubing becomes incompatible with the protection against infection afforded by the hazmat suits that medical professionals were required to wear.  

Still, in the US, such items as device accuracy and reliability, among many others, remain unapproved even if this sort of certified testing might have been performed during the R&D process. With these cautions in mind, the Stemoscope‘s brand name shares four letters “STEM” with a now-famous educational acronym (Hefferman, 2019): Science, Technology, Engineering and Mathematics, where the device has found one of its niches.  

The Stemoscope is a wireless, Bluetooth®-enabled stethoscope device that pairs with a mobile device such as an Android or Apple smartphone. The mobile device, equipped with a dedicated app, processes and amplifies the sounds captured by the Stemoscope, in turn sending them to Bluetooth®-enabled, or wired, earphones. The Stemoscope app (see animated gif below) instructs on where to position the Stemoscope on your chest to listen to heart and lung sounds, and on your arm for blood pressure sounds. The app also enables storage of recordings for archiving, sharing, and emailing.

Two new apps, the PetStemo and BabyStemo, respectively enable users to listen to the heartbeats of their pets and baby in-utero. The Babystemo app also offers to record in-utero sounds for reassuring playback to newborn infants, or for sharing with family and friends. In other words, couples no longer need to wait for prenatal visits to hear their baby's heart beating.

Below, an animated gif of the Stemoscope app, together with images of two Stemoscope models: the Standard and the PRO. 


The more recent PRO version is able to pair directly with Bluetooth®-enabled earphones for listening to sounds, without recording; or to pair directly to Bluetooth®-enabled smartphone and PC for listening to sounds, without earphones. The PRO model also has a noise-canceling function, as well as longer battery life. Pink and blue-colored models of the standard version also exist.

Oh, patents! GoldieBlox™ engineer & inventor

Copyright © Françoise Herrmann

Move over Barbie™, there’s a new superstar in town! Her name is GoldieBlox™!

Designed “for girls who are thinkers that tinker”, the GoldieBlox™ construction story kits are designed to teach engineering and building concepts (i.e. spatial skills) to young girls (7+ years) while banking on girls’ strong verbal and story building skills.

In a world where only 14% of the engineers are women, this toy and its creator, Debbie Sterling, herself a Stanford Mechanical Engineering graduate, are out on a mission! The mission is none other than to level the playing field in STEM (Science, Technology, Engineering and Math).  Beginning with “disrupting the pink aisle”,  that is, making waves in those sections of toy stores dedicated to princesses and fairies for little little girls, the idea is that little girls might also be introduced to engineering and building at a very early age, so they may learn to love this activity as much as Debbie.

The rest is history!...It took 6 months for Goldieblox™  to sell nationwide at ToyRus! GoldieBlox™ has also won some impressive toy awards: The 2013 Parents Choice Award (Gold Award), two 2014  Toy of the Year Awards (in the People’s Choice & Educational Toy categories) and a place in the 2014 list of Best of Apple Apps. GoldieBlox™ also has 250,000+ followers on Facebook, 20 million + YouTube views, 15 million TV viewers, and 4 billion Media impressions! Hip, hip, hooray for GoldieBlox™!

The GoldieBlox story-construction kits offer a narrative playworld of characters at Bloxtown: Goldie Blox, nicknamed “G”, a mechanical engineer and inventor; Ruby Rails, nicknamed “Rubes”, a software engineer “who lives life by her code” and designs her own clothes with a program called “Dress Code”; Li Gravity, a guy nicknamed “Heights”, who loves physics and who is Goldie’s lifelong friend and neighbor; Valentina Voltz, nicknamed “Val” or “vv”, who loves gadgets and works with circuits and electricity; and a cast of 4  little creatures: Nacho (the pooch), Benjamin Cranklin (the cat), Lucky (the fish), and Katinka (the pink dolphin). Thus, for example, you will find a construction story kit called “Nacho’s cat nook” where Goldie Blox sets out to build a multi-story cat nook, with an elevator, to cheer up Benjamin Cranklin, the grumpy cat! The lever engineering principle is at work in this construction story kit and the 40 parts it contains are all designed to develop fine motor skill, problem-solving and spatial skills!

The invention of these construction story kits is disclosed in US2014199677 (A1) ― 2014-07-17, titled Modular multi-element constructions from rearrangeable pieces and kits allowing construction of same.
Board-based machines assembled from components including crank and winch attributes which allow for coupling between the components, and which allows the user to position various elements into desired positions. A kit of components including coupling attributes which allow for assembly into a large number of different types of machines and structures of different types and shapes. A book adapted to teach children about mechanical aspects of design in concert with a kit of components adapted to be used to create board based machines. [Abstract US2014199677]
