From a comment on last week’s post about a self-made Lego lie detector, we’ve been tipped off about the enormous sales of galvanic skin response and biofeedback devices.
While we cover new relaxation techniques and devices, we hadn’t realized how thoroughly galvanic response had moved from lie-detection into self-help. Indeed, we’ve come a long way since the days of subliminal stop-smoking tapes and hypnotism:
There is a small, hand-held and self contained GSR2 which has sold a half a million units and is already the largest selling Galvanic Skin Response monitoring device for home biofeedback. The GSR2 precisely monitors your stress levels by translating tiny tension-related changes in skin pores into a rising or falling tone. By resting two fingers on the sensing plates you learn to lower the pitch and your stress level.
The GSR Temp 2X also includes a temperature sensor for monitoring heat levels in extremities. Stress also reduces blood flow to the hands, causing cooling. The GSR/Temp 2X home biofeedback system allows you to do “hand warming” biofeedback in addition to training with the GSR2 monitor, temperature sensor, body sensors for hands-free use, dual-sensitivity meter, earphone, instruction manual and a cassette with a short relaxation program.
