In this article we describe the re-embodiment of biological aggregation behavior of honeybees in Jasmine micro-robots. The observed insect behavior, in the context of the insect’s sensor–actor system, is formalized as behavioral and motion-sensing meta-models. These meta-models are transformed into a sensor–actor system of micro-robots by means of a sensors virtualization technique. This allows...

Silk cocoon membrane (SCM) is an insect engineered structure. We studied the electrical properties of mulberry (Bombyx mori) and non-mulberry (Tussar, Antheraea mylitta) SCM. When dry, SCM behaves like an insulator. On absorbing moisture, it generates electrical current, which is modulated by temperature. The current flowing across the SCM is possibly ionic and protonic in nature. We exploited ...

A monolithically integrated ISFET sensor array and interface circuit are described. A new high-density, low-power source-drain follower was developed for the sensor array. ISFETs were formed by depositing Au/Ti extended-gate electrodes on standard MOSFETs, then thin silicon nitride layers using catalytic chemical vapor deposition and/or SU-8 protective layers were formed on the extended-gate el...

In this work, we grow different types of carbon nanotube (CNT) forests directly on AlNbased electroacoustic biosensors and study their functionalization efficiency. CNTs are used to increase the effective surface area of the sensor, pursuing a better sensitivity, without increasing the sensor capacitance. Here we use a general method for CNT bio-functionalization with specific receptors for tar...

This paper presents Cantion’s cantilever-based bio/chemical sensor. The cantilevers have integrated readout and can be used both in liquids and gases. The sensing principle is based on a cantilever bending due to a change in surface stress. Such surface-stress change is obtained during molecular interaction which has made it possible to measure DNA hybridization, antigen-antibody interactions e...

This article comments on green aspects of (bio)chemical sensors for qualitative and quantitative analysis applications. First, the that connect chemical biosensors with main trends analytical chemistry are discussed. To continue, a set paradigmatic examples sustainable assays pertaining to (bio)sensing field have been selected explored in some their variants. These use smartphone camera togethe...

In this paper, a highly monolithic-integrated multi-modality sensor is proposed for intracorporeal monitoring. The single-chip sensor consists of a solid-state based temperature sensor, a capacitive based pressure sensor, and an electrochemical oxygen sensor with their respective interface application-specific integrated circuits (ASICs). The solid-state-based temperature sensor and the interfa...

We protein engineers are ambivalent about evolution: on the one hand, evolution inspires us with myriad examples of biomolecular binders, sensors, and catalysts; on the other hand, these examples are seldom well-adapted to the engineering tasks we have in mind. Protein engineers have therefore modified natural proteins by point substitutions and fragment exchanges in an effort to generate new f...
