-For medical/research use, Empatica E4 wristband is a wearable wireless device that offers PPG, EDA, 3-axis accelerometer, and optical thermometer sensing. Through its mobile API the following data are made available in real time: blood volume pulse at 64Hz and inter beat interval time pair obtained from the PPG sensor; electrodermal activity at 4Hz; XYZ raw acceleration at 32Hz; and skin temperature at 4Hz. The current list price on their website is 1,690 USD. +For medical/research use, Empatica E4 wristband is a wearable wireless device that offers PPG, EDA, 3-axis accelerometer, and optical thermometer sensing.

 BITalino BVP finger clip is a wired transmission-mode sensor that works in conjunction with other BITalino sensors that are sold separately or as part of a sensor kit. It offers a preconditioned analog output with a high signal-to-noise ratio currently retailed at €240 as standalone or paired with an all-in-one board (MCU, power, and Bluetooth) for €65. BITalino BVP finger clip is a wired transmission-mode sensor that works in conjunction with other BITalino sensors that are sold separately or as part of a sensor kit.

-For biofeedback training, FDA-certified NeXus EXG is a wired sensor kit that measures BVP in conjunction with other biosignals such as EDA, respiration, and temperature. It uses proprietary carbon technology alongside active noise cancellation that measures the external noise and subtracts it from the signal. +For biofeedback training, FDA-certified NeXus EXG is a wired sensor kit that measures BVP in conjunction with other biosignals such as EDA, respiration, and temperature.

 Valencell, a company producing high-performance PPGs, offers their sensor package (hardware, optomechanical design, firmware and algorithms) to be integrated into wearable (wrist/arm bands) and hearable (earbuds) designs. Their PPG is equipped with active signal characterization to remove noise from optical signals during heavy activity and challenging environments coupled with a low-power accelerometer.  Valencell, a company producing high-performance PPGs, offers their sensor package (hardware, optomechanical design, firmware and algorithms) to be integrated into wearable (wrist/arm bands) and hearable (earbuds) designs.
