Face to Face

11.06.2013 by Ben Lane

In an age when office mates bridge the 10 foot communication chasm between their desks with email and text messages, Key Tech actively recruits engineers and designers that enjoy and excel at the lost art of face-to-face communication.

Working with Complicated Disposable to Instrument Interfaces

04.25.2013 by Eric Schneider

Lab on a Chip, Microfluidics, and Sample to Answer are terms we hear a lot when designing medical devices. For years the trend has been to integrate more and more laboratory functions into small disposable chips or cartridges with the ideal goal of being able to perform all the functions from sample preparation to detection in a single disposable on one instrument. This has led the instruments disposable interfaces to be increasingly complex. Sometimes there are hundreds of electrical connections for internal sensors or actuators, multiple heaters for PCR amplification, systems for magnetic bead capture, pressure connections for fluid control, actuators for dispensing stored fluids, and external sensors just to name a few. The complex interfaces required can cause many design challenges, but after working on several of these types of projects over the years we’ve learned there are some ways you can make your life easier, and end up with a better design.

TED Talks: Designing for the Real World

09.12.2012 by Chet Larrow

TED Talks over the last couple of years has published many inspiring and informational pieces and has become a staple for those working in creative industries. The relevance of the one floating around the KeyTech office this past week was no exception.

If you’ve been waiting for a reason to get started on something, now is the time. Seth Godin’s new book, “Poke the Box” might give you the push off the branch you need to really fly.

When life gives you lemons, make a lemon battery!

Inside most kitchens, a lemon leads a normal life, being integrated into a delicious dish or drink. But many science students have found in their classroom experiments that a lemon is no mere fruit.

Medical Device Interoperability

07.27.2010 by Chad Schneider

Is it possible to verify and validate the safety and efficacy of medical devices if they could be connected to unknown current and future products? The medical device industry is working with the FDA to work out the safety issues of device interoperability.

Collecting very fine volumetric accuracy data

06.29.2010 by Chad Schneider

As part of the V&V test procedure, we designed a gravimetric means to characterize the volumetric and flow-rate accuracy of a couple of precision injection instruments. With this setup, we’re able to achieve measurement resolution of just 0.1 milligram and reduced the error due to water evaporation to 40 times better than using a mineral oil emulsion.

Learn by doing

05.25.2010 by Chad Schneider

I don’t learn anything new from examining a design for the 23rd time. I’ve checked for mistakes, but it’s all based on what I already know and a few educated guesses. The only way I can learn more is by building.

Sit still for a great idea

05.18.2010 by Chad Schneider

Making progress feels good, but when progress slows or I’ve hit a roadblock, it can be frustrating. When I need some fresh ideas, it’s time for a distraction.

The symbiosis of modeling and prototyping

02.23.2010 by Chad Schneider

Prototypes are essential to testing system performance. However, due to the current technological constraints of creating microscale prototypes, compromises in the characteristics of the prototype usually must be made, which can lead to unforeseen, expensive problems on the production line. Fortunately, basic, fundamental models of significant aspects of the system (first-principles modeling) can be “calibrated” through the use of focused CFD models and empirical data. The result is improved models that allow the designer to bridge the knowledge gap between paper and production.
