Over the past decade nonscientific research has experienced a pronounced improvement with respect to the number of recording sites integrated on implantable neural probes. This increase in channel count is reflected to a certain extent also in the number of light sources integrated on MEMS-based tools used in optogenetics enabling a depth-dependent stimulation of tissue at minimal tissue damage.
The talk will discuss recent results on optical tools with integrated light-emitting diodes (LEDs) implemented either as thin film LEDs or LED-chips. It will describe the key technologies to realize these devices and their opto-electro-thermo-mechanical characterization. In vivo applications will be discussed used to stimulate neural tissue, the cochlea and cardiac tissue. Among others, the local temperature increase caused by the optoelectronic building blocks will be extracted in tissue phantom and the perfused heart.
