Feel is getting close to releasing a rather svelte looking wristband that recognizes five basic emotions (happy, angry, sad, stressed and satisfied). The device is equipped with four bio-sensors, Bluetooth LE and is waterproof. The bio-sensors are:

• HRV – Heart Rate Variability
• GSR – Galvanic Skin Response (sweat)
• ST – Skin Temperature
• IMU – Inertial Measurement Unit (IMU) 

The HRV is being accomplished with the use of a Blood Volume Pressure (BVP) sensor.  Feel includes a companion app to help track emotions on a calendar level. The goal is to determine where, when and during what activities with whom cause patterns in emotion.
