I've used lots of different cans and generally they work fine.
A fingertip electrode as supplied by Ralph Hilton is basically a rectangle of thin tin roughly 6cm x 4cm (guess from memory) that you bend around your finger for a personalized fit. The sharp edges are taped so they don't slice into the skin. They work fine, in some ways better than cans as you don't have to grip them and there is less body motion from tightening or relaxing the grip. You can get some body motion showing by "clenching" the fingertip but you have to work at it.
Has anyone tried medical-type sticky electrodes? They are a bit like bandaids and come in all shapes and sizes. They are cheap. On eBay UK a typical price is 4 for £3 including postage. Description:
• Dimensions: 40 x 40 mm (1.5" x 1.5").
• Connectors: Standard 2mm jack compatible with most stimulation, pain relief and monitoring equipment.
• Typical applications: muscle building, biofeedback monitoring, toning and all types of acute and chronic pain.
• The electrodes are pre-gelled: no need for messy electro-conductive gel!
• Suitable for long term repeated term use on a single patient.
• Latex free.
Any comments? Assuming they work for e-meters, I would think they would be great for researching what the meter actually reads. Fingertips have lots of nerve endings. Thighs not so many. It is hard to do a comparison by sticking cans onto various body parts, I found.
