1. A portable and integrated system for testing tactile threshold, vibration perception, thermal perception and measuring temperature of a skin of a limb, the system comprising:
a tactile threshold testing module, wherein the tactile threshold testing module comprises a pointed filament pressed on a foot of a person to induce a set of touch sensation at predetermined locations on a limb of the person and record a feedback through a feedback module:
a vibration perception testing unit module comprising a combination of vibration motors, a spring and a damping mechanism, and wherein the vibration perception testing module is configured to induce a set of vibrations at the predetermined locations on the limb of the person and record feedback through the feedback module;
a thermal perception testing module, and wherein the thermal perception testing module comprises two Peltier modules, a plurality of temperature sensors and a plurality of temperature probes, wherein the two Peltier modules are bolted to a cooling fin and a fan arrangement, and wherein the thermal perception testing module is configured to induce a set of temperatures at the predetermined locations on the limb of the person and record feedback through the feedback module;
a skin-temperature measurement module, wherein the skin-temperature measurement module comprises an infra-red thermometer, and wherein the infra-red thermometer is configured to measure a temperature of the skin of the person through a non-contact process, and wherein the skin-temperature measurement module includes a LED pointer, or a laser pointer, for focusing or pointing the infra-red thermometer at an area to be measured on the skin;
a power control module;
a computing module; and
wherein the cooling fin and the fan arrangement is designed to dissipate heat from the Peltier modules, and wherein the plurality of temperature sensors and the plurality of temperature probes are mounted on the Peltier modules, and wherein the plurality of temperature probes are designed to induce a temperature variation, and the plurality of temperature sensors are designed to measure a temperature variation at the predetermined locations on the limb of the person and wherein the temperature variations are within predetermined ranges both above and below the ambient temperature.
