Compression vests are specialised clothes designed to use light, evenly distributed stress to the wearer’s torso. They’re generally used as a therapeutic instrument to handle numerous sensory processing and sensitivity points, nervousness, stress, and impulsive conduct. These vests work by offering a comforting, reassuring sensation that may assist people regulate their sensory experiences and emotional state.

The precept behind compression vests is rooted within the idea of deep stress stimulation, which has been widely known for its calming and organizing results on the nervous system. The stress utilized by the vest prompts proprioceptive enter, which refers back to the physique’s consciousness of its place and motion in house. This enter helps people really feel grounded and related to their our bodies, selling a way of safety and stability.

A number of business compression vests are available on the market, they usually sometimes use a small hand pump for inflation. That is positive for a lot of instances, however an engineer that goes by the identify Tevian realized that automating the method couldn’t solely allow some fascinating new capabilities, however might additionally make these vests accessible to people who are disabled, who couldn’t in any other case inflate them on their very own.

With this concept in thoughts, Tevian developed a customized machine referred to as Auto-Inflate . Designed to have a comparatively small footprint in order that it may be hid in a pocket, Auto-Inflate can mechanically inflate a compression vest and has some compute energy to allow superior features like timed inflation-deflation cycles. Auto-Inflate was developed to work with the business product referred to as The Squease Vest, however Tevian believes this machine may very well be simply tailored to another compression vest.

An air pump and solenoid are used to inflate and deflate the vest below the management of an ESP32 microcontroller. This {hardware}, and the supporting parts, had been assembled on a customized PCB. A second PCB was designed to deal with the person interface — a small OLED show display screen and an encoder to offer the Auto-Inflate with person inputs. A stress sensor was leveraged to find out when the inflation course of needs to be stopped. The {hardware} is housed in a customized case to guard the parts whereas they’re stowed away in a pocket. The system is powered by rechargeable batteries and has been proven to be able to totally inflating a vest in about ten to fifteen seconds.

Auto-Inflate remains to be very a lot a piece in progress, and Tevian is actively exploring methods to make the machine higher. Including extra sensors is being explored, as is swapping out the microcontroller for a board such because the Arduino Nano 33 BLE Sense for its built-in Bluetooth radio and inertial measurement unit. That Arduino might additionally come in useful if Tevian decides to run down the thought of utilizing a machine studying algorithm to find out when and how you can set off vest inflations based mostly on sensor measurements — it was instructed that this sort of system might cease an issue earlier than it will get began.

Whereas all the things has been working based on plan, an emergency shutoff button was added that bodily disconnects the {hardware} from the facility supply simply in case of an issue. And this is a crucial characteristic that shouldn’t be missed, as Tevian notes that the Auto-Inflate can generate sufficient stress that it might severely constrict inhaling a small little one.

The Auto-Inflate could also be one thing of a distinct segment machine, however this totally different method of approaching the inflation course of might have numerous utility and profit many individuals. Particularly, placing synthetic intelligence to work to cease signs earlier than they’ve an opportunity to get began is intriguing. Nonetheless the acronyms would possibly get complicated — the AI-powered AI? In any case, it is a nice thought, and we actually hope that Tevian will proceed work on this mission and see it by way of to completion.An automatic inflation system enhances compression vests (📷: Tevian)
