For electrical stimulation, generally, the lower the electrode salt content, the less skin irritation the subject will experience; this is because fewer salt ions are driven into skin during stimulation. This strategy puts more demand on the stimulator, because skin impedances are higher with low salt electrodes. There is no one size fits all requirement. For example, it’s possible to help mitigate the undesirable effects of higher salt content electrodes by stimulating the subject with bipolar pulses, instead of unipolar pulses.
SOLID gels are gentler on the skin than WET gels at the same salt concentration. This is due to the higher water content in the WET gels that make them react faster and more aggressively on the skin.
We do not recommend for applications running more than 24 hours.
Possible skin irritation can result from the gel or the adhesive on the body of the electrode.
Note—About 2 % of the population will react to any adhesives and gels put on a skin, regardless of composition or concentration.
The STMTHERM is a thermal stimulator that can deliver both hot and cold temperature stimulation to a subject. The STMTHERM can be used to identify participant thermoreceptor response thresholds for a variety of applications. The STMTHERM consists of two parts, the Stimulator Control Unit (SCU) and the included Thermal Stimulation Transducer (TSD191 Thermode) to deliver temperature […]

It can physiologically be observed through an increase in heart rate, respiratory rate, blood pressure, oxygen availability, and other mechanisms. In […]
HRV, EMG, and EEG studies using BIOPAC hardware and software include: DON’T STRESS Humans encounter various stressful situations everyday at work, home, and school. Such stress when experienced at high degrees and/or for a long duration of time could lead to cardiovascular diseases, cognitive dysfunctions, and psychological disorders. This study examined the validity of a novel physiological measurement […]
