Sensors and FHE need each other: a look inside a key relationship

by Wilfried Bair
Senior Engineering Manager for Device Integration and Packaging, NextFlex

Flexible hybrid electronics (FHE) and sensor technologies are a perfect match for each other. Nearly every current application of FHE technology that either NextFlex or our partners are working on involve sensors, so it’s beneficial for both platforms to grow and thrive alongside each other. Of course, these benefits ultimately carry down to the applications that use both FHE and sensors, such as chemical sensing systems and human health/fitness monitoring devices. When we drill down into this topic, it shows a unique symbiotic relationship that’s critical to the development of next-generation manufacturing.

Printed sensors and electronics: development challenges and emerging applications

As new sensor technologies continue to proliferate in existing and emerging applications, one especially promising area is printed-electronic sensors. We recently spoke with Dan Brewer, Executive Director of Marketing and Intellectual Property at Brewer Science, an active participant and one of the early entrants into this technology segment. The privately held company is based in Rolla, Missouri and was founded by Dr. Terry Brewer in 1981. The company got its start in semiconductor materials and specifically in materials used in front-end processes. They still claim to hold the largest market share in anti-reflective coatings for semiconductors, and they produce 70-80 types of materials used in lithography processes. From front-end materials, the company expanded to back-end advanced packaging materials, and from there to printed electronics.

MEMS foundry SilTerra unveils monolithic PMUT on CMOS platform

SilTerra, a Malaysian CMOS and MEMS foundry services provider, this week unveiled a piezoelectric micromachined ultrasound transducer (PMUT) on CMOS platform for fingerprint sensing and medical imaging applications.
