BetterSkin™ Electrodes
WPI's new BetterSkin™electrodes are high quality Ag/AgCl reusable surface-mounted electrodes designed to be used for the acquisition of all biopotentials. Each electrode is fabricated using an optimum quality sintered Ag/AgCl pellet encased within a strong epoxy housing designed to have an extended lifetime. “stamped” metal electrodes and Ag/AgCl disposable electrodes, WPI's BetterSkin electrodes provide increased stability, lower noise and lower offset voltage during surface biopotential recording. These features are particularly important during measurement of very small potential signals, such as EMG or EEG recording.
Four BetterSkin electrode sizes are currently offered: 7 mm, 13 mm, 16 mm and 19 mm (OD). The 7 mm electrodes are designed for use where close spacing between biopotential recording sites is required. The medium sized electrodes (13-16 mm OD) are general purpose electrodes and appropriate for most applications. The 19 mm large size electrodes are designed for optimal surface skin contact for use during long-term biopotential recording.
Ag/AgCl Probes
EE1 - Flat Epoxy Probe 4.5 mm OD x 50mm; 3.5 mm sensor diam. 25 mm 20 ga. tinned cooper wire
EG1 - Glass 1mm x 3mm sensor, 1mm glass shaft x 50 mm, 25 mm x 0.25 mm silver wire
Three different connector and cable combinations are offered: a 2 mm pin with 1 meter unshielded cable; a 2 mm pin with 1 meter shielded cable (shielding is connected to an additional 2 mm grounding pin); and 1.5 mm DIN safety socket with 1 meter unshielded cable (the 1.5 mm DIN safety socket will fit WPI’s DBA digital biological amplifier and most of modern input design bioamplifiers). All electrodes require adhesive disks (e.g., WPI's ADD200 series) and recording gel
