Small, pre-gelled, electrodes. Most appropriate for long-term ( > 2 hours ) biopotential measurements. The hydrogel base also lends these electrodes to electrical stimulation studies, such as for nerve conduction velocity or tDCS. These disposable, long-term recording, snap electrodes provide the same signal transmission as reusable electrodes, with added convenience and hygiene. Each peel-and-stick electrode is pre-gelled and designed for one use only.
Use disposable snap electrodes with any BIOPAC lead specified for snap electrodes (e.g. LEAD110 series). For best performance, use shielded leads (e.g., the LEAD110S) for recording electrodes and an unshielded lead (e.g., LEAD110) for the ground electrode.
