Zytronic Touch Sensor Technology Chosen for New Blood Analysis System

  • Location:  Sweden
  • Industry:  Medical
  • Application:  Industrial & Factory Automation

Introduction

The rugged, touch sensors developed by Zytronic, utilizing its patented and highly scalable Projected Capacitive Technology (PCT™), have been incorporated into a wide spectrum of product designs serving a multitude of commercial markets. There are few applications, however, that place as exacting demands on touchscreens as those relating to healthcare. The company’s proven success here has now been further cemented by a project with Scandinavian medical equipment manufacturer Perimed.

Zytronic is supplying the touchscreen that makes up the user interface of Perimed’s latest portable transcutaneous oxygen monitoring equipment for utilization in hospitals – the PeriFlux 6000. The specially designed 8.7” ZyBrid® touchscreen is constructed from 3mm thick impact resistant toughened glass which has been further enhanced with a printed border, featuring the Perimed logo, product name. The glass surface of the sensor is also anti-glare treated to improve the visibility of displayed information under direct lighting.

Zytronic PCT touch sensors, are constructed with an XY matrix of ultra-fine (10μm diameter) copper capacitors embedded into a durable laminated glass substrate.  Unlike conventional resistive and surface capacitive touch sensors, the technology is effectively invulnerable to all forms of mechanical stress (scratches, impacts, vibrations, etc.), as well as extreme temperatures and harsh chemicals. In addition, while optical, infrared (IR) and surface acoustic wave (SAW) touch technologies usually depend on the inclusion of a bezel, in which the transmitting/receiving electronics are housed, PCT touch sensors support smooth-fronted, edge-to-edge glass designs. This means that the high levels of hygiene critical in medical applications are much easier to maintain, as there are no recesses in which dirt and germs can be trapped. The touch sensors also have the advantage of being able to detect touch through a glove – and notably in this application – even when the glove is made of latex or rubber.

“Our engineering team was greatly impressed with the attributes exhibited by Zytronic’s touch technology. By incorporating it into the PeriFlux 6000, we can have total confidence that this instrument will deliver high quality results consistently, with no compromise in performance.””

Björn Bakken, President of Perimed
