MRISAR's Interactive Pentiductor Exhibit
This is a technological, interactive, responsive exhibit that allows the user to become part of the exhibit as it reacts differently to people by creating various sound patterns depending on the individual’s conductivity. The device conducts a small electrical signal, which turns on an oscillator, which creates sound patterns. As more users touch the plates the sounds develop deep tonal qualities that are reminiscent of musical notes. Optionally many people can use the device together in a number of ways such as having one person touch the large plate and another person touch a small plate and then in turn touch their remaining hands together. Additional people can be added to form a chain between the two users who are touching the large and small plates. The key is to make sure you are touching each other’s skin for conductivity to take place. The device is also able to work with single arm operation should a user have a disability that prevents two-hand use or even with amputee limbs.
To operate it, touch the metal circle of the Large Touch Plate with one hand and a metal circle of one of the Small Touch Plates with the other hand at the same time. Figuratively in electrical terms, think of the Large Touch Plate as its positive terminal and the Small Touch Plates as its negative terminal and your body as its conductive wire. We originally designed and fabricated this exhibit in 1993. It is an exciting educational exhibit that delights both young and old. It features a touch sensitive oscillator, which produces sound patterns in relation to how the touch plates are operated. It is of moderate weight for portability, easy to use and extremely durable. The five-sided design makes it adaptable to fill inner floor spaces and to work with both single users and groups.
This device uses an Optoelectric Isolated Power Supply (LED Light source and Solar Panel) to power a touch sensitive oscillator, creating a low voltage, ultra-low current signal, to harmlessly pass through the human body to activate its circuit, thus producing sound patterns. This illustrates how energy can be converted from electric to photonic back to electric, stored and utilized electrochemically, then oscillated and converted into an IR signal and back again into an electrical signal and then amplified.
The exhibit touch circuit operates on a totally isolated power supply at approx. 6 VDC and requires a grounded 120 V AC outlet. A Solar powered version is available upon request. The text supplied on the exhibit discusses theory, technology and applications. The exhibit is available in a wide variety of color options. This exhibit is an example of alternative energy, sensory inputs and reactionary effects in electronic systems, conductivity, timing and randomizing theory, visual and wave length specific electromagnetic emissions, photons, sound synthesis, frequency and amplitude, acoustics, touch switch technology, energy conversion, photovoltaic and photonic science, electrical conductance and oscillator theory.
Size is 36" diameter x 36" high.
