Cornell University researchers who build nanoscale electronics have developed microsensors so tiny, they can fit 30,000 on one side of a penny. They are equipped with an integrated circuit, solar cells and light-emitting diodes (LEDs) that enable them to harness light for power and communication. And because they are mass fabricated, with up to 1 million sitting on an 8-inch wafer, each device costs a fraction of that same penny.
NUS researchers develop microsensor implants smaller than a pencil tip for round-the-clock health monitoring
A research team from the National University of Singapore has developed an advanced wireless technology that can detect microsensors tiny enough to be injected under the skin.
