Biosensing Systems
 
 

 

QUASAR is the world leader in innovative noncontacting bioelectric measurement and monitoring systems. We have demonstrated continuous technological improvements and increasing system sophistication since we began our bioelectric sensing work in 2001. Our current standard biosensors deliver measurements off the skin, through hair and even through clothing. This proprietary sensing technology can be optimized to perform for ECG, EEG, EMG, and EOG applications. QUASAR integrates our biosensors with our finely tuned hardware and sophisticated algorithms to develop precise, robust, low power systems that are comfortable enough to encourage user compliance and robust enough to deliver information under difficult conditions.

 

Advantages:
 •
Noninvasive
 • No skin preparation
 • No gels or adhesives
 • Excellent artifact rejection

Applications:
 • Cardiac diagnostics
 • Physiological monitoring
 • Cognitive state monitoring
 • Human-Computer interface



Core Technology

QUASAR has developed two types of bioelectrodes upon which our systems are based.

True Capacitive


• Fully insulated capacitive dry electrode
• No charge exchange with skin
• Works through clothing
• Proprietary feedback-based grounding
• No gels, pastes. Wearer can put on in 30 seconds

Hybrid, Part Capacitive, Part Resistive



• Dry Ag or Ag/AgCl contact to unprepared skin
• Spring mount, controlled force dry electrodes
• Designed to work through hair
• Rounded fingers to part hair
• Proprietary feedback-based grounding
• No gels, pastes. Wearer can put on in 30 seconds
