Wearable sensors provide continuous, real-time information of physiological biomarkers via dynamic, minimal/non-invasive measurements. The global market of wearable sensors is growing expeditiously from $ 32.63 billion in 2019 and expected to $ 105 billion in 2027 at an annual growth rate of 15.9% 1 , 2 . There is an unlimited scope to investigate the biomedical, agricultural, environmental, and security applications of portable and wearable sensors as the significant research themes. Innovative strategies in the fabrication of non-invasive and minimally invasive wearable sensing devices facilitate the continuous monitoring of vital biomarkers in physiological body fluids viz., sweat, tears, saliva, interstitial fluid, nasal fluid, etc. Wearable sensors have been developed on distinct platforms such as microneedles, bandages, textiles, tattoos, gloves, eyeglasses, rings, and mouthguards. The horizon of wearable sensors is extending in various ways (i) for real-time monitoring of pathophysiological biomarkers/ions for health management such as diabetes, Parkinson, Alzheimer’s, Cancer, etc., (ii) for assessing the environmental hazards by identifying potential chemical threats such as nerve disrupting agents, explosives, opioids, and gunshot residues, etc., (iii) for the agricultural/food products screening for herbicides, mycotoxins, etc. Apart from these, harnessing energy from sweat and tears using non‐invasive and minimally‐invasive enzymatic biofuel cells to power wearable/implantable devices have also found considerable attention in the recent past. My research talk starts with a brief introduction to the basic components and importance of biosensors and wearable sensors, then elaborately discusses the key research accomplishments attained, highlights the challenges and further scope of the research themes, and concludes with a succinct outline of my future research proposals. My perspectives on establishing the laboratory at the Department of Chemical Sciences, Indian Institute of Science Education and Research Mohali are stated as well.
