Transdermal Skin Patches Market to Develop with New Innovation that Enables Tracking Multiple Health Indicators Simultaneously

Posted On March 18, 2021     

Day by Day, engineers are getting closer to the development of a skin patch that would have the ability to monitor several types of health conditions and would come to replace some of the most expensive medical equipment. In regards to this, a team has developed a new soft and stretchy skin patch that an individual can wear to monitor his/her medical condition. It can keep track of one’s BP (Blood Pressure), HR (Heart Rate), lactate, caffeine, alcohol, and glucose levels, all at the same time.

The new product is a massive development in the Transdermal Skin Patches Market as its availability in the market could provide several benefits to those patients who need to continuously track multiple health indicators. It would be great for individuals with diabetes, heart diseases, or patients in the intensive care unit. The positive aspect of this device is that a lot of sensitive information can be acquired by using non-invasive ways without disrupting an individual's work or interrupting their daily activities.

In order to test the patch's efficiency, the device was tested on numerous types of subjects, who were performing various tasks, like drinking an alcoholic or caffeinated drink, exercising, and high-sugar meal. It concluded that the readings were approximately the same as that of a commercial monitoring device. Researchers' novel approach here was that they used completely different sensors and merged them together on one small platform that was as small as a stamp. The patch produced is a thin sheet made of stretchy polymers that consist of BP sensors and two chemical sensors. One sensor is measuring lactate (a biomarker of physical exertion), alcohol, caffeine in sweat, and the other sensor is used for measuring glucose levels.

The device monitors blood pressure with the help of a sensor wielded to the patch by a conductive ink. Measurements were taken by applying a voltage to the transducers, which in turn sends ultrasound waves. The waves bounce off the nearest artery and return an echo signal translated in a BP reading. The sensor that measures alcohol, lactate, and caffeine in sweat and is printed on the skin patch from conductive ink releases a drug by the name pilocarpine into the skin. This helps in the detection of chemical substances present in the sweat induced by the sweat.

The glucose sensor is basically an electrode that gives out mild electrical shocks to the skin, which stimulates the release of interstitial fluid and measures the glucose present in the body.

In designing this device, the team had to overcome two significant hurdles. The first was to optimize the layout, such as balancing the distance between all the sensors to prevent signal interference. The second was to pick the suitable ultrasound gel for BP sensors so that leakage into the other two sensors' hydrogels could be prevented. The team is now focused on adding even more sensors to the patch and making it completely wireless.
