in real time by directly quantifying the amount of cortisol – also known as “the stress hormone” – in the user’s sweat. Paired with our smartphone app, our comfortable armband device goes beyond stress measurement to provide automatic stress management 24/7. By activating a grounding cooling sensation, the device can moderate acute spikes in cortisol levels. Both chronic tracking of cortisol levels and improved moderation of cortisol levels has been shown to improve physical and mental health, and the E-Sentience solution brings the combination to market in a non-invasive and innovative solution.

based on their medical and behavioral history. It evaluates internal triggers through evaluation of physical parameters (e.g., steps, heart rate) and social media behavior (evaluated through AI). It considers external triggers through news alerts and self-reported wellbeing. MYND automatically checks in on the user’s mental health when they are in distress. After providing an evidence-based risk assessment to evaluate the intenisity of the crisis, it provides resources tailored to the user’s problem, language, and profile (ethnicity, faith, age, and other). Furthermore, MYND opens the space for vulnerability and strengthens peer support by having a “ping your friend” feature, where the user can check in on a friend’s mental health with one click. MYND includes customizable coping skills lists. It creates a space for help, support, and awareness.

I am a medical doctor from Germany. While working during the pandemic I realised the burden of mental illnesses and struggles in the population. I enrolled in a Masters of Public Health at UC Berkeley to make a difference on a broader level. I started working as a volunteer crisis counselor at the LIfeline. With these new exposures, I quickly realised where key problems in mental health care lie, and what opportunities are ahead. That is when the idea of MYND started to form.
