• Wristify

    A touch of cool – or warmth – just when you want it.


    Coming soon to early adopters who join our mailing list.


    We lent Wristify to strangers. Here are their reactions.


    What is it?

    The first bracelet that heats or cools you.

    Wristify is developed by a team of MIT-trained engineers who are using cutting-edge technology to revolutionize temperature.

    What does it do?

    Thermal relief. Anytime, anywhere.

    Wristify recreates the relief you get when you warm your hands by the fireplace in the winter, or when you refresh with an ice cube on your skin in the summer.

    Does it change my core temperature?

    Think of your hands by a fireplace.

    Wristify doesn't need to modify your core temperature to make you more comfortable. Wristify draws on 30 years of thermal research to maximize comfort in a discreet and energy-efficient way.

    But isn't it only acting on my wrist?

    Targeted relief is what our body needs.

    Studies show that local warmth or cold gives you a body-wide sensation of thermal comfort. This is exactly what happens when you dip your toes in the cold water on a hot sunny day at the beach, or when you place a warm washcloth on your forehead on a cold evening.

    When can I buy it?

    Coming soon!

    We are working hard to develop the Wristify bracelet as fast as possible. Stay tuned and subscribe to our newsletter to find out as soon as Wristify becomes available.


    EMBR labs was founded by four MIT students who are passionate about letting people take control of their own comfort.


    Our mission is to harness the power of temperature to improve personal comfort and to save energy. We are driven by the realization that existing temperature solutions haven't significantly evolved in the last hundred years: these solutions are passive, low-tech, and impersonal.


    EMBR Labs is revolutionizing temperature by developing a core technology and consumer products that deliver greater physical well-being and energy efficiency than is currently possible with heating, ventilation and air conditioning systems or clothing alone. Our team of MIT-trained engineers has been working tirelessly since 2013 to leverage cutting-edge engineering and advanced materials to make thermal comfort solutions that are elegant, simple and personal.


    EMBR labs benefits from the ongoing mentorship and support of the Trust Center for MIT Entrepreneurship, the MIT Venture Mentoring Service, and is partnering with leading academic research groups. Since winning the first prize of the MADMEC competition at MIT in 2013, our company has been the recipient of multiple prizes and awards.


    We are also hiring! If you are interested and live in the Boston area, email us at jobs@embrlabs.com.
