Researchers on the Massachusetts Institute of Expertise (MIT) have unveiled a solderless breadboard designed with wearables very firmly in thoughts: the FlexBoard, which does precisely as its title suggests and bends to adapt to virtually any floor form.
“A elementary improvement in our trendy world is that we will work together with digital content material all over the place and anytime, which is enabled by means of ubiquitous interactive gadgets. FlexBoard helps the design of those gadgets by being a flexible and speedy interplay prototyping platform,” explains co-author Michael Wessely, assistant professor, of the crew’s work. “Our platform additionally permits designers to shortly check completely different configurations of sensors, shows, and different interactive parts, which could result in quicker product improvement cycles and extra user-friendly and accessible designs.”
Like some other solderless breadboard, a FlexBoard permits the consumer to insert and take away parts at-will while not having to solder or wire them into place. In contrast to rival designs, although, the FlexBoards can bend to adapt to curved surfaces — just like the human hand or arm — utilizing a 3D-printed “dwelling hinge” sample to attach every bit to its neighbors.
The core idea of FlexBoards is similar to CurveBoards, one other MIT analysis effort unveiled again in March 2020 and designed to make it simpler to prototype digital circuits for wearables or unusually-shaped gadgets. The place the form of a CurveBoard is mounted on the time of manufacture, although, the FlexBoards are actually versatile — making it potential to reposition them or alter their form at any level in the course of the prototyping course of.

“Whereas designing new interactive gadgets, consumer interfaces, or most digital merchandise, we often deal with the item kind and digital capabilities as two separate duties, which makes it exhausting to check the prototype in its use atmosphere within the early stage, and may result in integration points additional down the highway,” claims co-author Junyi Zhu. “FlexBoards deal with these points with enhanced, reusable versatile breadboards, which speed up the present interactive machine prototyping pipeline, and supply a brand new and beneficial prototyping platform for the low-power electronics design and DIY group.”
To show the idea, the crew put collectively a sequence of demonstrations of FlexBoard-powered prototyping which might be tough utilizing conventional breadboard designs: including sensors and LEDs to kettlebells to observe the consumer’s kind and supply suggestions throughout train; a collision warning system added to digital actuality controllers; and wearable gloves which may seize the consumer’s gesture, once more for feeding into digital actuality. The FlexBoards have been examined for 1,000 bends with no harm, and will be taken off prototype objects for re-use, the researchers say.
For the time being, nonetheless, constructing a FlexBoard is a really gradual course of: the plastic portion is 3D-printed, making it tough to provide in quantity, and {the electrical} contacts have to be assembled by hand.
The crew offered its work on the 2023 CHI Convention on Human Elements in Computing Programs, with full particulars out there on the challenge web site together with a replica of the paper underneath open-access phrases.
