The biotech company Sensimed has developed a contact lens that monitors the user’s glaucoma:
The Triggerfish lens is made of the same silicon hydrogel as many of the soft contact lenses currently on the market, but embedded within it is a microprocessor and a strain gauge that encircles its outer edge. When fluid accumulates in the eye, the diameter of the cornea changes, and that change is picked up by the strain gauge. Data is processed and then transmitted via radio frequency to a receiver.
This data can then be used by doctors to provide specific and timely treatments, as well as give researchers a continuous stream of data about the progress of the disease in the same patient.

Computer security expert Tadayoshi Kohno says that biotechnology that has a neural interface, such as advanced prosthetic limbs, may make the brain accessible to hackers in the future:
In some cases, patients might even want to hack into their own neural device. Unlike devices to control prosthetic limbs, which still use wires, many deep brain stimulators already rely on wireless signals. Hacking into these devices could enable patients to “self-prescribe” elevated moods or pain relief by increasing the activity of the brain’s reward centers.
Despite the risks, Kohno said, most new devices aren’t created with security in mind. Neural engineers carefully consider the safety and reliability of new equipment, and neuroethicists focus on whether a new device fits ethical guidelines. But until now, few groups have considered how neural devices might be hijacked to perform unintended actions. This is the first time an academic paper has addressed the topic of “neurosecurity,” a term the group coined to describe their field.
