Wearable- IOT based low- cost platforms can enable dynamic lifestyle monitoring through enabling promising and exciting opportunities for wellness and chronic- disease management in personalized environments. Diabetic and pre- diabetic populations can modulate their alcohol intake by tracking their glycemic content continuously to prevent health risks through these platforms. We demonstrate the first technological proof of a combinatorial biosensor for continuous, dynamic monitoring of alcohol and glucose in ultra- low volumes (1-5 µL) of passive perspired sweat towards developing a wearable- IOT based platform. Non-invasive biosensing in sweat is achieved by a unique gold- zinc oxide (ZnO) thin film electrode stack fabricated on a flexible substrate suitable for wearable applications. The active ZnO sensing region is immobilized with enzyme complexes specific for the detection of alcohol and glucose through non- faradaic electrochemical impedance spectroscopy (EIS) and chronoamperometry (CA). Biomolecular interactions occurring at the electrode- sweat interface are represented by the impedance and capacitive current changes in response to charge modulations arising in the double layer. We also report the detection of alcohol concentrations of 0.01-100 mg/dl and glucose concentrations of 0.01-50 mg/dl present in synthetic sweat and perspired human sweat. The limit of detection obtained for alcohol and glucose was found to be 0.1 mg/dl in perspired human sweat. Cross- reactivity studies revealed that glucose and alcohol did not show any signal response to cross- reactive molecules. Furthermore, the stable temporal response of the combinatorial biosensor on continuous exposure to passive perspired human sweat spiked with alcohol and glucose over a 120-min duration was demonstrated.

Tex Rickard, famed promoter, at whose behest innumerable great fists have done their devastating work, and strong men fallen and been jeered for falling, took in his hand a steam drill with which he intended to drive the last rivet one made of solid brassinto the framework of the new Madison Square Garden, Manhattan. A workman turned on the steam. The driver began to chatter and jump about in the promoter's grasp. He perspired freely. Neither his great brain nor his little thews could prevail to make the yellow rivets sink to its place....

Sitting by a window on a damp, melancholic afternoon, sipping on a warm cup of tea, I often sink into a slumber of nostalgia. The elaborate designs engraved on the cup are gazed upon and knitted on with a paralysed index finger, as the perspired rim is circled on with the thumb. The steam emanates from the surface of the tea, evaporating into an abyss of thick air. I find myself lost amidst various thoughts and the crisscrossed complexities of life. A look into the bygone years and my aching heart pulsates for the sight of Ma. Her insights into the edges and the cores of the house have always been admirable. The power and the strength within her raise life within my corpse. Every element within the house premises locks a distinctive memory of Ma.
In June 1984, Kagaa, a small village in the Kikuyu highlands of Kenya, enjoyed a fine mist of rain filling the air of the ridges dotted with coffee bushes. Kinuthia, a fourth-year student at Kagaa High School, climbed these hills, leaving him perspired and chilled at the same time, but most of all feeling gratitude for the mist. Although it left him damp, the rain was considered a blessing by Kikuyus, even when there was no drought. The coffee was making a slow recovery from the devastating drought of the previous year, a crisis that prompted the donation of grain from the United Nations, and the butchering of the village cows and goats for lack of grass in the highlands. Kinuthia was also grateful for the hills of the highlands and for the practice they provided him in long distance running as he strode the red clay tracks etched into them to and from school daily. These hills contributed to his becoming a local star in the high school track competitions' 5000 meter race. Today was his last race as an O-level student, unless he won and qualified for nationals. There was also the good chance he would ace his O-level exams and gain admission to an A-level school for further education. If that happened, he could continue running at one of those bigger national schools where he had hoped to study chemistry and become a pharmacist. He never wanted his livelihood to fall victim to relentless heat and sunshine again.
A forehead perspiration collector and discharger constructed primarily of various sizes of vinyl or rubber tubing. The larger sized tube of the device having absorption apertures rests upon the wearer's forehead for taking in perspired fluids whereby the smaller tubes direct any contained excess fluids out to the rear discharge site. An elastic cord is joined to sliding cord retainers which rides over the tubular sides of the device which serves as an adjustable enclosure for securing to a wearer's head.
1. A forehead sweat absorption device for collection and discharge of forehead perspiration including a means for adjustable attachment to the wearer's head, wherein said device functions by collecting and disposing of perspired fluids through a transfer process via tubing canals, 2ff7e9595c
