PS25255 EPIC Ultra High Impedance ECG Sensor

Plessey Semiconductors Electric Potential Integrated Circuit (EPIC) product line targets a range of applications.

The PS25255 is an ultra high impedance solid state ECG (electrocardiograph) sensor. It can be used as a dry contact ECG sensor without the need for potentially dangerous low impedance circuits across the heart. The resolution available is as good as or better than conventional wet electrodes.

The device uses active feedback techniques to both lower the effective input capacitance of the sensing element (Cin) and boost the input resistance (Rin). These techniques are used to realize a sensor with a frequency response suitable for both diagnostic and monitoring ECG applications.

Applications

Contact ECG signal detection for:

• Non-critical patient monitoring equipment.
• Emergency response diagnostics.
• Lifestyle sports and health products.
• Suitable for long-term and remote monitoring.
