Plessey release consumer ECG product

Plessey Semiconductor have released an consumer ECG monitor based on their EPIC chip. Called imPulse, it works by a user just holding the device with their thumbs and then displays the ECG on a smartphone or tablet connected via Bluetooth.

The devices contains two Plessey PS25201 EPIC sensor (one for each thumb) and the software on the smartphone/tablet can perform simple analysis to display the heart rate.

The sensors work by detecting the electrical potential in the air (about 100V per metre of height) and the disruption caused by the human electrical signals.

The sensors can also be used for non-contact heart rate detection, but there is a lot more ambient noise to remove and requires more complex software for analysis.

The EPIC sensors can also be used to detect people through walls using clever software.

iECG my new start-up idea

I'm developing an ECG monitor that uses a new chip/sensor that allows ECG measurements to be taken by placing the sensors on or near the body.

Some hardware will be developed that will do the filtering/digital signal processing work based on ARM CPU and the clean signal can be displayed on consumer hardware such as an iOS or Android phone/tablet or even a PC. There are many consumer applications such as heart rate monitoring for general health, sports activities and such like. The system could also be used to monitor babies by placing the sensors into a cot and check for things like Sudden Infant Death Syndrome (SIDS). There's also real medical uses such as in ambulances as utilising a sensor that can be wiped clean has many cost saving advantages to current ECG pads which cost around $20 a set and are single use.

Plessey introduces EPIC sensors

Plessey Semiconductor has introduced a new sensor based on their Electric Potential Integrated Circuit (EPIC) that be used for ECG (electrocardiogram) applications.

The sensors don't work in the same way as existing ECG systems in that they measure the electric field instead of the actual voltages, so the sensor can detect an ECG from 2 conductive sensors (say in each hand) rather than having multiple sensors attached to the body in various places to get a good signal (the current sensor pads are covered with gel and are not re-usable and cost about $2 a set). The EPIC system can use cleanable sensors so can be used continually.

The detection of electric fields is similar to magnetic field detection.

The sensor can detect as low as 1mV p-p.

Voltage in the atmosphere is around 100V per (vertical) metre and the human body being made up mainly of water can distort this field, therefore the sensor has other uses as it can detect people (moving or entering an area) even through walls.

If the system really works, it could have huge benefits for the health system and sensors could be incorporated into lots of devices like stretchers or even hospital beds.

The people detection applications would fall more into security and other services.
