Single-element miniature force sensor delivers superior sensitivity

SingleTact was designed to address just that. It is an ultra-thin, single-element capacitive sensor that accurately and reliably quantifies forces and delivers incredible performance including less than 1% repeatability errors in addition to being more than 3X the sensitivity of resistive force sensors.

“It is remarkable how our sensor technology advanced from my Harvard days two decades ago when we developed tactile sensors for robotic applications. To date, our sensors have been primarily used by Fortune 500 companies but now with SingleTact, every engineer, whether a university student, government institute or a commercial company is able to capture force data more accurately and reliably than ever before“, says Dr. Jae Son, Founder and CEO, PPS.

SingleTact empowers engineers to develop innovative products and projects where precise and reliable force measurements arerequired using open source software and firmware. A complete turnkey solution is available to engineers wishing to collect force data either in analog or digital configuration, while the versatile SingleTact interface board, which allows easy analog or digital I2C integration, can be customised for engineer’s own application. A choice of six sensor configurations is provided including 8mm and 15mm diameter sensors and a variety of force ranges from 100 grams to 45kg full scale.

SingleTact is suitable for OEM customers wishing to provide the "sense of touch" to innovative products they are developing. The core technology has been implemented in various cutting edge products. Standard SingleTact configurations can be evaluated quickly using turnkey data collection solution featuring open source sample code for Arduino and Windows PC application, while custom designed sensors are available for meeting specific OEM application requirements.

Nearly 20 years of proven track record in developing capacitive tactile sensors allow PPS to successfully work with OEM customers through all stages of development from sensor design to the manufacturing of millions of SingleTact force sensors.

“SingleTact makes our sensor technology more accessible. It is a lot simpler and more affordable than any other sensor we ever developed before, while maintaining our sensor performance heritage. Using SingleTact, OEM customers can develop more innovative products and make a positive impact on the world,” Dr. Son added.
