A research team of scientists of the CSIR, Karaikudi, Tamil Nadu, has created a portable low-cost, wearing sensor which is able to track the health and physiological state of the human body by analysing the sweat in the process. The CSIR CECRI is based in Karaikudi, Tamil Nadu.The microfluidic sensor can be used to concurrently detect multiple biomarkers from sweat samples on location such as lactate, sodium and potassium.
The biomarker is analysed without messages being passed on. The sensor’s high-performance sweat samples enable continuous sweat capture and transportation around the platform floor, leading to real-time analysis. A fluid channel in the sensor senses sweat in real-time and guides it for subsequent interference-free analyses by active sensing electrodes. A miniaturised printed circuit board captures cross-speaking, non-driven sensor responses.
A paper on their study has been published in the journal ‘ACS Sensor’ by the Team headed by Dr. Vinu, a recipient of an INSPIRE Faculty fellowship initiated by the Science & Technology Department, Government of India. They also investigate other biofluids like saliva and fluid in tissues, since they are equipped with plentiful chemicals that represent the basic physiology of the human body. In addition, portable power storage systems are being designed to power wearable electrical sensors.
The team has, with the power of a wearable pulse frequency sensor, designed a versatile and extended solid-state supercapacitor as an energy buffering element.
