Premo
Master Thesis – marked with a 9.

Stress (and Anxieties) complaints tend to be more pervasive in today’s life. Reducing levels of stress is becoming of more importance for mental wellbeing. The crossover between stress and ever more present wearable technology show such devices would be promising. Deep Pressure Touch (PDT), pressure on the body, is known for its therapeutic calming effect. Derived from this the wearable device ‘Premo’ has been developed and its effectiveness of ability to reduce stress levels and on task performance-related stress. A tailored system had to be designed because of the lack of existing adaptive DPT systems and the novel inclusion of the rhythm instead of continuous pressure.


Feedback on the project: To be able to do what Mark did he had to take the role of not only a researcher, but also a maker, designer, prototyper and artist and in my opinion he took each of these roles seriously and really achieved something in each of these aspects of the project. Behind almost each final decision is a thorough investigation, even to the point of user-testing different types of hugs! The final product is not just a thesis, but also a working prototype for Premo, a design plan that other DIY enthusiasts can follow to make their own and a whole series of intermediate products that use other techniques that have been attempted (like motors instead of air etc).


  • Premo is my graduation project which was praised with a 9.
  • My master thesis, ‘Calming pressure: a study through design on stress reduction by deep pressure touch contractions through wearable technology’, can be found here.

Placement of the wearable: Choosing the right location for this is key because some areas of the body are more intimate than others and the wearable could potentially be too invasive. Different body parts convey a different meaning when ‘used’ because of culture. For Premo, Inspiration was drawn from ‘hugging’ because of its close connection to calming, soothing, comfort and safety. After an initial pilot study with real participants, different kinds of hugs were examined and analysed.
Premo is no cure – but rather it is trying a new way to have the potential to serve as an inspiration to help people suffering from chronic stress and anxiety.
User testing, after several user-test, the data was statistically analysed.
Building Premo required different skill sets. Parts are self designed and 3d printed.
