# Fatigue-Sensing Tattoos This Biosensor is a Temporary Tattoo That Alerts Athletes of Over-Exertion By Laura McQuarrie | Published 2013-07-29 | Lifestyle Source: Trend Hunter, https://www.trendhunter.com/trends/biosensor References: [gizmodo](http://gizmodo.com/this-biosensor-knows-when-your-body-will-quit-before-yo-915791462) & [acs.org](http://www.acs.org/content/acs/en/pressroom/presspacs/2013/acs-presspac-july-24-2013/first-human-tests-of-new-biosensor-that-warns-when-athletes-are-.html) This [biosensor tattoo](https://www.trendhunter.com/trends/biostrap-kairos) is a technology designed to help athletes and soldiers from over-exerting themselves. The sticky sensor is adhered to the skin during a workout and [monitors stamina throughout](https://www.trendhunter.com/trends/kinexon-sports) to determine the point at which a person can't physically work out any more. This technology is able to detect the point at which an athlete will "hit the wall" by measuring the [levels of lactate produced in sweat](https://www.trendhunter.com/trends/molesense). At a specific threshold, a certain level of lactate production indicates that the body is near fatigue and can't push any harder. Currently, lactate-measuring methods are long processes that require drawing blood samples. This non-invasive technology will be useful for informing athletes of their thresholds instantaneously to help to maintain a healthy workout regime without completely exhausting themselves in the process. ## Trend Insights (Trend Hunter) - Score: 2.4/10 - Popularity: 33% | Activity: 32% | Freshness: 8% - Audience gender: 90% men, 10% women - Primary generations: Millennial, Gen X - Top markets: North America, Asia ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Lifestyle](https://www.trendhunter.com/lifestyle) > [Health](https://www.trendhunter.com/health) ## Key Themes ### Key Themes Behind This Trend - **Non-invasive Biosensors:** This trend highlights the opportunity for developing biosensors that can monitor various bodily functions without invasive procedures. - **Real-time Performance Monitoring:** This trend showcases the potential for wearable technologies that can provide athletes and soldiers with real-time data about their physical performance to prevent over-exertion. - **Instantaneous Health Feedback:** This trend identifies the need for technologies that can provide individuals with immediate feedback on their health-related thresholds to optimize their physical activity and prevent exhaustion. ### Where This Applies - **Sports Technology:** This industry can explore the development of innovative biosensor devices and wearable technologies tailored for athletes to enhance their performance and prevent injuries. - **Fitness Trackers:** This industry can incorporate lactate-measuring capabilities into their wearable devices to provide users with real-time feedback on their physical exertion levels and prevent fatigue. - **Healthcare and Wellness:** This industry can leverage non-invasive biosensors to provide individuals with personalized health monitoring solutions, helping them optimize their fitness routines and prevent over-exertion. ## Related on Trend Hunter - [Athletic Sweat-Tracking Wearables](https://www.trendhunter.com/trends/hydrosense-ai-sweat-sensor.md) - [Sweat-Wicking Wearable Biosensors](https://www.trendhunter.com/trends/hydration-biosensor.md) - [Wearable Sweat-Analyzing Patches](https://www.trendhunter.com/trends/sweanty.md) - [Perspiration-Analyzing Fitness Trackers](https://www.trendhunter.com/trends/sweat-fitness-tracker.md) - [Sweat-Analyzing Hydration Wearables](https://www.trendhunter.com/trends/nix-hydration-biosensor.md) - [Muscle-Monitoring Health Wearables](https://www.trendhunter.com/trends/muscle-oxygen-monitor.md) - [Stretchable Sweat-Activated Yarn Batteries](https://www.trendhunter.com/trends/yarn-battery.md) - [Rapid Cardiac Protein Sensors](https://www.trendhunter.com/trends/wrist-sensor.md) - [Wearable Hydration Monitors](https://www.trendhunter.com/trends/connected-hydration.md)
