Robotic Walkers


Designed by a team led by Assistant Professor Yu Haoyong at the National University of Singapore, this robotic walker hopes to help patients in rehabilitation centers get back to walking more quickly.

From a gizmag article: “…the omni-directional platform supports the patient’s body weight as they walk across the floor, while also providing powered support for movements of their pelvis and trunk. Force sensors detect the direction in which the patient wishes to move, and respond by moving the walker with them in that direction.”

App for Group Conversation Captioning for the Deaf


From the company website: “Transcense is developing a technology that can empower 360 million deaf and hard of hearing people on the planet.” Advertised as an application that helps people hear group conversations, this application has many potential uses. As you can see from the quote above, one of the most important is related to helping deaf and hard of hearing people function in group settings. This could help greatly in academic (i.e. school) and workplace (i.e. meeting) settings. Read more at:


“Do you need a taxi?” “No! I need a vaccine.”


Many people know about UBER, the smartphone app that allows a person to order a cab via their smartphone. In November of 2014, UBER had a one-day, on demand free vaccine day that allowed people in Chicago to use UBER to order a flu-vaccine instead of a Taxi. This was the fourth city where UBERHealth was available. For more info check out:

3D-Printed Jaw

I wanted to follow up the general 3-D printing post with a tangible post about 3-D printing in healthcare. Here is the first of many to come. In India, we have now seen a customized 3-D printed jaw inserted into a cancer patient who had to have parts of his upper jaw an palate removed. Read more at:

“What’s That Mean?”: 3-D Printing

I would like to continue the “What’s that Mean?” series by exploring the concept of 3-D Printing. To start with, let’s define the term by sharing the definition from the Oxford dictionary. “A process for making a physical object from a three-dimensional digital model, typically by laying down many successive thin layers of a material”.

Originally 3-D printing referred to processes that “sequentially deposited material onto a powder bed with inkjet printer heads” (wikipedia).  Now 3-d printing contains processes like  Photopolymerization, Bioprinting, and Nanoscale 3D printing. 

What this means for someone like me, who doesn’t actually know the definition of Nanoscale 3D printing, is that we are now entering an age where 3-D printing will allow incredible, almost miraculous achievements. In future articles, I will cover such creations as a 3-D printed jaw, a 3-D printed skull, elegant printed 3-D printed prostheses, and 3-d printed casts.

e-Liiso Mobile Eye Checkup


To combat preventable blindness (in the form of trachoma) in Uganda, IT student Moses Rurangwa formed Sight for Everyone, a company which has developed an eye checkup app called e-Liiso. In March 2014, they took third place in the BigIdeas@Berkeley contest.

From site: “Doctors and optometrists using e-liiso will be able to check patients’ abilities by just taking a flash picture from a phone camera to see color, test for long and short-sightedness, and also detect the presence of cataracts and other eye conditions. The app uses smartphones’ cameras, flashlights and display to check how the eyes react to stimuli, while doctors can also track the progress of individual patients and easily keep a record of their geo-location.” Read more at:
