Xth Sense

The Xth Sense™, XTH’s first product, is a wearable musical instrument based on original biophysical technology. It captures sounds from heart, blood, and muscles and enables anybody to create and play interactive music with the inaudible sounds of their bodies.

The Xth Sense consists of a tiny slick wearable with an organic and soft-touch feel that can be worn either as a patch, for use while resting, or as an armband for use during physical activity. It is designed to feel like an integral, natural part of the body. The wearable is embedded with a unique array of biosensors, including bioacoustic sensors, a body temperature sensor, and a 9-degrees-of-freedom IMU unit, which includes an accelerometer, a gyroscope, and a magnetometer. The bioacoustic sensors capture sounds from the heart beating, blood flowing, and muscles contractions, which describe how movement is generated inside the body. The body temperature sensor tracks the increase and decrease rate of body heat, which is associated with intensity of activity and stress levels. The IMU unit captures three-dimensional data that describes the movement of the user’s body in space.

The sounds and data from a user’s body are then sent over a wireless connection to several dedicated apps. Here, the software algorithms extract salient features from the data array and then associate those features to musical parameters.
