Plessey Semiconductor has developed an Electric Potential Integrated Circuit Sensors that are touted capable to "easily and discretely incorporated inside the vehicle seatbacks to access the necessary biometric signals and provide earlier warning of drowsiness or health issues than systems based on eye or head movement". The company also says that their sensor can capture the person's electrocardiogram (ECG) and sense the electrical impulses of the heart without direct skin contact and can return an accurate R peak signal from the users ECG which can be used to calculate HRV. This is a very impressive breakthrough. I have tried to use the sensors but I cannot get them to work as advertised. In short, I cannot get the any ECG signal at all. I was wondering if there is anyone on this forum who has ever used the sensor and if he/she is willing to share his/her experience using the sensor.
