The wearable sports gadget described is a wristband designed to measure blood lactate levels and muscle tension threshold. Unlike existing models that require a blood sample, this gadget uses two impedance probes and an IR sensor to measure blood impedance and oxygen levels in the blood. It can detect when the body is in an anaerobic state, indicating the presence of lactic acid. Additionally, a piezoelectric sensor on the back of the wristband records body vibrations to measure muscle tension threshold. This data can help athletes monitor their performance and make adjustments as needed, such as using an oxygen mask. Overall, this wearable gadget offers a convenient and non-invasive way to monitor vital health indicators while engaging in physical activity.
