A temperature sensor based on a MWCNT/SEBS nanocomposite

New Developments in Smart Bandage Technologies for Wound Diagnostics

“…The latter include: pH, [16][17][18][19][20] bacterial metabolites, [21][22][23] endogenous wound biomarkers, [ 24 ] volatile organic emissions [ 25,26 ] and temperature. [ 27 ] Many of these have been investigated with the intention of implementation within a clinic setting, but acquiring suffi cient selectivity with minimal sample preparation is a severe challenge, especially when considering the limited time available during a patient consultation. At present, considerable attention is being paid to the measurement of wound pH.…”

“…[ 24 ] This can be achieved through a procedurally simpler approach, involving the amperometric oxidation measurement of uric acid, As a biomarker, it has the advantage of being found in relatively high concentrations and there is an extensive amount of literature on its electrochemical detection. [ 27 ] It is somewhat ironic to note that whilst the ease with which it can be electrochemically oxidized is often considered to be an interference in electroanalytical methods, it is this same property that has made it attractive as a biomarker in the present context. This approach has seen further refi nement by Wang and co-workers who have adapted the system for wireless recording of the wound urate concentration through the use of an enzyme based system.…”

Transport performance in novel elastomer nanocomposites: Mechanism, design and control

“…3 . 3 S t i m u l u s -r e s p o n s i v e e l a s t o m e r s e n s o r s a n d a c t u a t o r s Stimuli-responsive elastomers refer to elastomers that can respond to external stimuli, such as electricity [21], strain [9,[158][159][160], temperature [161] and solvent [162][163][164], as indicated by electrical conductivity behavior.…”

MWCNT/perylene bisimide water dispersions for miniaturized temperature sensors

“…31 The effective π-associations between PZPERY and MWCNTs suggested to us that these nanocomposites should function as temperature sensors, since both semiconducting and metallic Cl resistance sensitivity of only -0.004 K -1 , a value which is comparable to that found in metals. 6,32,33 Such low sensitivity was ascribed to the polymeric dispersants, such as poly(styrene-b-(ethylene-cobutylene)-b-styrene) (SEBS) 6 or poly(vinylbenzyl chloride) derivative with triethylamine, 32 and the insulating nature of these components limit the thermal and electronic conductivities of the nanocomposite. In the present paper, we explore the possibility that the highly conjugated core of the PZPERY surfactant will is able to produce higher performance (resolution) temperature sensors.…”
