Quasi-piezoelectric coaxial cable's embedded smart electronics enables IoT applications

EMFIT says its quasi-piezoelectric coaxial cable sensor "stands up to water and heavy loads, allowing compression, stretch or vibration to generate a charge or voltage proportional to the stress."

EMFIT, a Finnish company known for its electroactive ferroelectret sensors, sensor-integrated systems and the EMFIT QS quantified sleep monitor, is expanding into IoT applications with the introduction of the C-Series quasi-piezoelectric coaxial cable.

EMFIT says its coaxial cable design "ensures self-shielding for use in high EMI (electromagnetic interference) environments." The company says the new cable "has a unique, strong electromechanical response from the cellular ferroelectret polymer, allowing compression, stretch or vibration to generate a charge or voltage proportional to the stress." The cable can be spliced using standard coaxial splicing techniques.

Extremely rugged, EMFIT’s C-Series cable stands up to heavy loads and water. It includes a narrow band of proprietary electroactive material wound around the inner conductor comprised of 20 AWG stranded silver-plated copper wire. The cable is then braided, and jacketed with an extruded high-density polyethylene. Various lengths are available, with a standard spool of 50 meters.

EMFIT says its C-Series coaxial cable sensing technology works for applications including: vehicle classification and weigh-in-motion (WIM); security, such as fence and perimeter intrusion detection; acoustic microphones and hydrophones; structural and machine vibration monitoring.

“EMFIT is now positioned to offer a newly expanded range of IoT applications using the new C-Series cable sensor with embedded signal acquisition electronics, mobile data connectivity, and EMFIT’s real-time over-the-Internet operating server software,” comments Heikki Raisanen, EMFIT co-founder and CEO.
