First came an oscilloscope small enough to fit in your hand. Now, from the same inventor, comes an oscilloscope built into an ordinary-sized wrist watch. Gabriel Anzziani in Sarasota, Fla. is trying to fund his 'wrist scope' project on Kickstarter. The gizmo is based on the same design as a palm-sized scope he has already devised. Specs include 256KB Flash, 16KB SRAM, 4KB EEPROM Sharp Memory LCD display, and 400-mAh Li-Ion battery rechargeable via a micro USB connector. The scope even functions as a logic analyzer with eight digital inputs that are 3.3 V / 5-V tolerant with a maximum sampling rate of 16 MSPS.
In other words, the wrist scope might not be something you'd use to debug an Intel Core i7 processor design, but it certainly makes a statement about the person wearing it.
