“…Analysis of sweating patterns is also an important parameter, as this can indicate autonomic dysfunction. A straightforward method of sweat analysis could help in the diagnosis and treatment of various conditions that are affected by autonomic dysfunction, such as diabetes and hyperhydrosis [9], [10].…”

Abstract-Textile-based sensors offer an unobtrusive method of continually monitoring physiological parameters during daily activities. Chemical analysis of body fluids, noninvasively, is a novel and exciting area of personalized wearable healthcare systems. BIOTEX was an EU-funded project that aimed to develop textile sensors to measure physiological parameters and the chemical composition of body fluids, with a particular interest in sweat. A wearable sensing system has been developed that integrates a textile-based fluid handling system for sample collection and transport with a number of sensors including sodium, conductivity, and pH sensors. Sensors for sweat rate, ECG, respiration, and blood oxygenation were also developed. For the first time, it has been possible to monitor a number of physiological parameters together with sweat composition in real time. This has been carried out via a network of wearable sensors distributed around the body of a subject user. This has huge implications for the field of sports and human performance and opens a whole new field of research in the clinical setting. F.

“…sweat rates on different regions of the body. This may be used to identify autonomic nervous system dysfunction that may occur due to condition such as diabetes [14]. Monitoring sweat activity may also be useful in understanding and treating a condition known as hyperhidrosis which causes excessive sweating [14].…”

Abstract-Sweat analysis can provide a valuable insight into a person's well-being. Here we present wearable textile-based sensors that can provide real-time information regarding sweat activity. A pH sensitive dye incorporated into a fabric fluidic system is used to determine sweat pH. To detect the onset of sweat activity a sweat rate sensor is incorporated into a textile substrate. The sensors are integrated into a waistband and controlled by a central unit with wireless connectivity. The use of such sensors for sweat analysis may provide valuable physiological information for applications in sports performance and also in healthcare.

“…(19) Currently, quality-of-life questionnaires and indicators of patient satisfaction are often used for measuring the intensity of hyperhidrosis. On the basis of such reports, various attempts have been made to modify the extent of resection of sympathetic ganglia in thoracic sympathectomy in order to eliminate or reduce compensatory hyperhidrosis.…”

Objective: To compare individuals with and without hyperhidrosis in terms of the intensity of palmar and plantar sweating. Methods: We selected 50 patients clinically diagnosed with palmoplantar hyperhidrosis and 25 normal individuals as controls. We quantified sweating using a portable noninvasive electronic device that has relative humidity and temperature sensors to measure transepidermal water loss. All of the individuals had a body mass index of 20-25 kg/cm 2 . Subjects remained at rest for 20-30 min before the measurements in order to reduce external interference. The measurements were carried out in a climate-controlled environment (21-24°C). Measurements were carried out on the hypothenar region on both hands and on the medial plantar region on both feet. Results: In the palmoplantar hyperhidrosis group, the mean transepidermal water loss on the hands and feet was 133.6 ± 51.0 g/m 2 /h and 71.8 ± 40.3 g/m 2 /h, respectively, compared with 37.9 ± 18.4 g/m 2 /h and 27.6 ± 14.3 g/m 2 /h, respectively, in the control group. The differences between the groups were statistically significant (p < 0.001 for hands and feet). Conclusions: This method proved to be an accurate and reliable tool to quantify palmar and plantar sweating when performed by a trained and qualified professional.Keywords: Hyperhidrosis; Sweat; Dermatology/instrumentation. ResumoObjetivo: Comparar a intensidade de transpiração em palmas das mãos e planta dos pés de indivíduos portadores de hiperidrose com a de um grupo controle. Métodos: Foram selecionados 50 pacientes com diagnóstico clínico de hiperidrose palmoplantar e 25 indivíduos controles. Um método objetivo de quantificação da transpiração foi utilizado com um aparelho eletrônico portátil, não invasivo, com sensores de umidade relativa e de temperatura capazes de quantificar a perda de água transepidérmica. Todos os indivíduos apresentavam índice de massa corpórea de 20-25 kg/cm 2 e permaneceram em repouso por 20-30 min antes das medições para reduzir a interferência externa. A mensuração foi realizada em sala climatizada com a temperatura de 21-24°C. Os locais determinados para a aferição foram região hipotenar da face palmar e região medial da face plantar. Resultados: No grupo com hiperidrose palmoplantar, as médias da intensidade de transpiração nas mãos e nos pés foram de, respectivamente, 133,6 ± 51,0 g/m 2 /h e 71,8 ± 40,3 g/m 2 /h, enquanto, no grupo controle, essas foram de 37,9 ±18,4 g/m 2 /h e 27,6 ± 14,3 g /m 2 /h. As diferenças das médias entre os grupos foram estatisticamente significativas (p < 0,001). Conclusões: Este método de quantificação mostrou-se uma ferramenta precisa e confiável na avaliação da transpiração palmar e plantar, quando operado por um profissional treinado e capacitado.Descritores: Hiperidrose; Suor; Dermatologia/instrumentação. * Study carried out in the
