EMFIT rolls out C-Series quasi-piezoelectric coaxial cable sensor
EMFIT’s quasi-piezoelectric coaxial cable sensor
EMFIT, the Finnish company known for its electroactive ferroelectret sensors, sensor-integrated systems and the EMFIT QS quantified sleep monitor, expands into new IoT areas with the introduction of the C-Series™ quasi-piezoelectric coaxial cable.
EMFIT’s coaxial design ensures self-shielding for use in high EMI (electromagnetic interference) environments. It 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 EMFIT’s 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 metres.
“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,” said Heikki Raisanen, EMFIT co-founder and CEO.
EMFIT’s C-Series™ coaxial cable sensing technology works for:
- Vehicle classification and weigh-in-motion (WIM)
- Security, such as fence and perimeter intrusion detection
- Acoustic microphones and hydrophones
- Structural and machine vibration monitoring
