      When standard solutions just don’t measure up to the job… (25/10/2017)

      Designers and specifiers of electronics hardware usually have a couple of simple options. Either their requirement is easily defined, in which case searching for available suppliers is relatively straightforward; or the requirement cannot be easily identified and found – or worse still, the specifier ends up making a poor choice based on ‘closest match’.

      Problematic pacemakers (25/08/2017)

      During the French Revolution, beheading was the preferred method of execution. The guillotine was used for thousands of executions, meaning there was no shortage of experimental material for biologist Marie Francois Bichat. Bichat tested the electrical stimulation of hearts, which was instrumental in the development of the modern day pacemaker. Nowadays, pacemakers are commonly used to maintain a regular heart rate. This article looks at how electrical interference can led to pacemaker issues.
