摘要:
Disclosed are appendage mountable electronic systems and related methods for covering and conforming to an appendage surface. A flexible or stretchable substrate has an inner surface for receiving an appendage, including an appendage having a curved surface, and an opposed outer surface that is accessible to external surfaces. A stretchable or flexible electronic device is supported by the substrate inner and/or outer surface, depending on the application of interest. The electronic device in combination with the substrate provides a net bending stiffness to facilitate conformal contact between the inner surface and a surface of the appendage provided within the enclosure. In an aspect, the system is capable of surface flipping without adversely impacting electronic device functionality, such as electronic devices comprising arrays of sensors, actuators, or both sensors and actuators.

To determine the heat or cold sensation or pain threshold of a human being, a thermode is applied to the skin of the subject under investigation, and the temperature is varied until the subject feels pain. This pain threshold temperature is maintained for a predetermined period of time and then the subject is requested to adjust the temperature until the same sensation is felt. The pain threshold temperature values obtained by this "tonic" method may be verified or improved by a "phasic" method of applying thermal stimuli, wherein pulse-type thermal stimuli (S1 to S8) are applied with randomly varying spacings (B1 to B7) and with temperatures varying between upper and lower limits (T m , T o ) randomly about the pain threshold temperature (T s ) established by the tonic method.

The invention relates to a device for assessing thermoalgesic and vibratory sensitivy, including a first unit (1) configured to apply, to localized points of the patient, a plurality of stimuli comprising vibrations and temperature changes, a second unit (2) for gathering data communicating with the first unit, wherein the communication between the first unit (1) and the second unit (2) takes place by means of a two-way wireless transmission means. The invention also relates to a method for assessing vibratory, thermal and thermoalgesic sensitivity using the device according to the invention.
摘要:
A configurable system is used to evaluate stimulus sensitivity of a subject. An action channel provides a stimulus to the subject and a reaction channel receives a response from the subject. A signal pathway is connected to the action channel and to the reaction channel. A controller establishes loops within the signal pathway. Loop types include a transduction loop including the action channel and forming a path terminating in the signal pathway, and a channel loop including the action channel and terminating at a reference unit. Other possible loop types include an interface loop including the action channel, the reaction channel and the reference unit having an initial parameter value, and an adaptive loop including the action channel, the reaction channel and the reference unit whose parameter value is adapted based on the response from the subject. A method using the system is also described.

Disclosed is a device for testing for the presence of neuropathy by applying a thermal stimulus to a test area of skin. The device includes a temperature sensing arrangement (1) for determining a reference temperature being a reference skin temperature or room temperature, a thermal stimulus application arrangement (3) and a temperature controlling arrangement (8) for controlling temperature of the thermal stimulus. The reference temperature is used in controlling the temperature of the applied thermal stimulus. The device may include a blood flow sensing arrangement (12) which provides a measurement of blood flow in an area of the skin which may be considered to be indicative of a blood flow in response to an applied stimulus.
