Do you mean **broken link removed**?

Electric Potential Integrated Circuit (EPIC) are basically 20 GOhm 15pF E field sensor/amps.

Disruptive EPIC sensor with multiple proven applications
High sensitivity electric potential sensor that can be used in either contact or non-contact mode
Contact mode: measures bio-electric signals like ECG, EMG, EOG and EEG
Non-contact mode: measures disruption in the electric field caused by human body movment enabling
Proximity sensing
Movement Sensing
Gesture recognition
Strong demand for products with major applications
Communications - smart-phones and tablets for ECG and proximity sensing
Consumer - remote sensing controllers for video games consoles
Automotive - alertness, occupancy and slow speed collision avoidance
Medical - ECG, tomography and "smart bed" applications
EPIC PCB hybrids and chips for all electric potential sensing applications
The integrated circuit provides a unique high impedance amplifier design
The PCB hybrid solution includes EPIC chip, tuning circuit and the sensor electrode
