![]() ![]() The Everysight Maverick smartglasses are a nice entry in the "simple and lightweight" category, just a heads-up display of basic information like navigation or fitness data. ![]() It's a standard-mount bracket to hold the tubes together, but it also includes a strain gauge so you get a readout of how much load your construction is experiencing. Lilikoi Innovation is a one-man company making force sensors for robotic actuators, but he also developed a neat product for the ubiquitous 8020 extruded-aluminum framework. The immediate applications are for surgical instruments or wristwatches, but it's just the sort of thing that could find uses all over the place in miniaturized, low-power devices.Īmfitrack demoed their electromagnetic motion tracker, using 3D coils with a very low-frequency radio transmitter to allow tiny sensor nodes to pick up their own position and orientation within 4 meters of a base station, without any drift like the normal style of inertial sensors are subject to. TiMach was showing off a MEMS micromotor, which uses a vibrating electrostatic drive hooked to a rotating ratchet wheel, clockwork-style. It uses a neat spinning-shutter electric-field sensor that I've never run across before, avoiding any need for a ground reference to measure the voltage against. Iona Tech has developed a wearable device to measure your body's static-electricity voltage before you touch a bare board on your electronics bench and zap it into the scrap heap. Not only is this at the picotesla level, but the amount of noise rejection they would have to perform in the middle of an electronics show is quite impressive. Neuranics had a demo of a frankly insane bit of sensing technology, picking up very clean ECG signals from the magnetic field of currents in the heart muscle. The news sites have covered the big launches, but here are the most interesting little things that I ran across in my embedded-systems world: I just got back from #ces2024 with 75,000 new steps on my pedometer. ![]()
