According to foreign media reports, biosensors that can be worn on the skin are expected to bring some exciting possibilities, because they may monitor the wearer’s daily health and even blood glucose or stress levels in a non-invasive way. Scientists from Binghamton University have made a breakthrough by making the device more comfortable to wear and producing clearer signals, as well as a new type of porous silicone that evaporates sweat. < / P > < p > it is reported that researchers used a silicone called polydimethylsiloxane (PDMS) as their starting point, which is often used in biosensor development due to its biocompatibility and flexibility. However, what this solid non porous material cannot provide is air permeability, which may cause problems in several aspects. “In motion monitoring, if you have a device on your skin, sweat will accumulate under it,” said Matthew brown, author of the study. This may lead to inaccuracies in the use of inflammation and continuous monitoring. ” < / P > < p > brown and his colleagues were able to produce porous PDMS by electrospinning, in which liquids first break them down into tiny fibers through an electric field. This method of production has led to a new material that behaves in mechanical tests similar to the collagen and elastic fibers of the human epidermis, while at the same time providing the stickiness that enable it to adhere to human skin. < / P > < p > the team tested the performance of porous PDMS through a series of experiments, and confirmed that it can make sweat evaporate and maintain high resolution signal during exercise. Therefore, the lower resolution of PDMS can not be used together with the natural evaporation signal of PDMS. In addition to sweat, porous materials also allow small molecules and gases to pass through. According to the team, this means that it can be combined with human tissues, opening up a range of possibilities, including wound healing, oxygen and carbon dioxide monitoring, and even implantable devices implanted into human cells.
