Using silicon-integrated circuit technology, we have fabricated a flexible multi-electrode array and used it for measuring evoked potentials at the surface of the ferret primary auditory cortex (AI). Traditionally, maps of cortical activity are recorded from numerous sequential penetrations with a single electrode. A common problem with this approach is(More)
—While RF energy harvesting has proven to be a viable power source for low-power electronics, it is still a challenge to obtain significant amounts of energy fast and efficiently from the ambiance. Available RF power is usually very weak, resulting in a weak voltage applied to a demodulator to drive it into a region of significant nonlinearity. An RF energy(More)

Integration of low dielectric constant Benzocyclobutene (BCB) film with deep etched structures in silicon allows the fabrication of MEMS devices with low parasitic loss. A fabrication process is developed for integration of thin BCB film and deep anisotropically-etched grooves in silicon using potassium hydroxide (KOH). Gold (Au) is used as an etch mask to(More)
— We present a novel two transistor synapse (" 2TS ") that exhibits spike timing dependent plasticity (" STDP "). Temporal coincidence of synthetic pre-and post-synaptic action potentials across the 2TS induces localized floating gate injection and tunneling that result in proportional Hebbian synaptic weight updates. In the absence of correlated pre-and(More)
