Is there anything new in the field of electrodes, sensors, etc. for EKG? We are developing a breakthrough set of cardiac disease-detection algorithms using a wearable garment and an on-body computer and communications device. The unit also needs to be MRI compatible, since one of our algorithms extracts a clear EKG signal, eliminating competing magnetoresistance and magnetohydrodynamic signals. The wet/dry electrodes and lead wires are areas of concern for us. @ Ask The Experts

There have not been many advances in the field of electrodes or sensors for EKG or ECG. However, you can implant flexible sensing bands in a wearable garment to detect any tension in either direction, monitoring changes in the behavior of the patient. The bands are normally provided with four wires for a full Wheatstone bridge configuration and would require 3- to 10-V dc regulated voltage to provide a 5- to 20-mV signal. It is possible to customize a miniaturized wireless sensor, but that would require very costly tooling and setup charges. The flexible sensing band can be specially designed and manufactured to be MRI compatible.
