Hackaday Prize Entry: Hand Tremor Suppression Wearable Device

It is extremely distressing to watch someone succumb to an uncontrollable hand tremor. Simple tasks become frustrating and impossible, and a person previously capable becomes frail and vulnerable. Worse still are the reactions of other people, in whom the nastiest of prejudices can be unleashed. A tremor can be a debilitating physical condition, but it is not one that changes who the person afflicted with it is.

An entry from [Basian Lesi] in this year’s Hackaday Prize aims to tackle hand tremors, and it takes the form of a wearable device that tries to correct the tremors by applying small electrical stimuli in response to the motion it senses from its built-in accelerometer. At its heart is an ATMega328p microcontroller and an MPU6050 accelerometer chip, and the prototype is shown using a piece of stripboard mounted in a 3D-printed box. It’s still in development and testing, but they have posted a video showing impressive results that you can see below the break, claiming an 85% reduction in tremors.
