Tactile Touchpoints

What's a key difference between ordinary products and smart products? Smart products have senses. Many of today's smart products can see and hear - but what can the sense of touch do to better serve the end user? By sharing real-world cases and idea-generating concepts, Tactile Touchpoints aims to inspire engineers of the world's smart products to consider how embedding tactile force sensors can create new outlets for advancement in their respective markets.

Figure 1: Thin position sensors, such as the strip sensor shown on the right, share many of the same functional characteristics of an electrical potentiometer (left). Thin linear potentiometers, or position sensors, are a unique component used to correlate the specific position of an actuator,...
Printed, thin, and flexible sensors have caused quite the buzz around the design engineering community in recent years. This is due largely to the boom of smart, lightweight, and power-efficient technologies, which have become entrenched in our everyday lives. Naturally, when designing these...
Ed Haidar, FlexiForce Product Manager and Applications Engineer, shares a story on how he helped a customer use Flexiforce sensors to correlate a change in voltage to a change in force -- otherwise known as a Relative Measurement Approach . For many devices or designs embedded with FlexiForce...
The Best Methods to Attach FlexiForce Sensors within Your Design
By working with a FlexiForce Application Engineer, your custom FlexiForce sensor can be designed with a peel-and-stick backing. FlexiForce sensors are a design-engineer-friendly embedded technology due in large part to their thin and flexible form factors. This allows them to be embedded into tight...
Fighting Back with the Power of Fun The story of a proactive father and his creative inventions that train his son to persist through the challenges of cerebral palsy. Meet Julian Nine years ago, Marc Gunderson’s son Julian was born three months prematurely, weighing just 1 kg (2.2 lbs) at...
This is the second of a two-part Tactile Touchpoints blog series summarizing the findings from a survey submitted to 373 members of the global design engineering community. The goal of the survey was to better understand what was most important to design engineers when selecting a supplier of...
The following is an independent 3rd-party study of High-Temperature FlexiForce sensor performance in their most extreme durability test to date. The complete citation can be found at the end of this article. FlexiForce™ sensors have shown the ability to maintain linearity and performance...
Voltage Divider or Op Amp Circuit -- Which Should You Choose?
Ed Haidar; FlexiForce Product Manager Here's another question we frequently receive from our customers - what is the recommended circuit to drive a FlexiForce™ sensor in an embedded design? If you've browsed our standard FlexiForce sensors recently, you’ll notice that we recommend an...
In the summer of 2018, we submitted a survey to 373 members of the global design engineering community to understand what was most important when selecting a supplier of embedded components. We will be sharing our key findings over a two-part Tactile Touchpoints article series. Question: Rank these...
No matter if your force-sensing application will endure more than a million actuations or just a few touches over its service life; validating sensor durability is a long and costly process for OEMs. One of the inherent values of using force-sensitive resistor technologies in an embedded...
